Does water (H20) conduct electricity?

Chemically pure water is an electrical insulator.\n\nEven the least impurity, even the least amount of any dissolved ion, will convert it into a conductor.  Even dissolved CO2 will provide the ionic activity to make water conductive

Hmm...  If I remember the physics right, it goes like this: Take two parts hydrogen and one part oxygen and mix them in a chamber with a catalyst and a proton exchange membrane and you get water and electricity.

You're not quite right. The dielectric of the solid (ice) is HIGHER than the dielectric of the liquid (water).\n\nAlthough water has a reasonably high dielectric constant (because the water  molecule has a dipole moment and so water can be polarized to virtually eliminate the field's effect), it still can act as a conductor because it always contains ions (OH- and H+ are always there, and also things like Cl- and Na+ are usually present) which are highly mobile.\n\nBeing conducting means that there is a current present whenever you apply an electric field, and the current means you have charge "leaking".  Yes, the reason water conducts well is because it is liquid, so ice is not a good conductor (though ice with a layer of liquid water on the outside would still probably allow quite a bit of current to flow).\n\nIn ice the water molecules have all lined themselves up in a fixed structure where the hydrogen bonds can be maximally satisfied. This means the dielectric relaxation time is higher, and the molecules can't realign themselves to a changing electric field easily. This corresponds to a higher observed dielectric constant.

I am assuming the energy in this context as "heat energy". Then the answer is NO. It depends on the temperature.\n\nHeat flows from body of high temperature to body of low temperature.\n\nImagine a small tank (10ltr) on second floor and a big tank with 100 lt on first floor. If we connect these, water flows from top tank to below tank.\nHeight is synonymous to Temperature.\nAmount of water is synonymous to Heat energy.\n\nPS: Another similarity is electricity.\nTemperature = height of water = voltage\nheat flow = water flow = current\nheat energy = amount of water = charge\nheat resistance = pipe resistance = electrical resistance

Electrolysis of water causes the formation of hydrogen peroxide with the result of rapid redox reactions that would cause gel to run way too fast. Also, while water can conduct electricity, it  heats up when electrified. Depending on the voltage, the water can get hot enough to melt the gel.

Yes , it is. And this from at least two view points:\n1) The salty marine water is a full of ions, so it represents  very clearly a electrolyte which is a conductive solution. All you need then is some electrodes which should have some differential potential in electronegativity. \n\n2)  The power of the waves which, there are already used as one of the alternative power producing  method. This is used either by actuating some radial turbines, or indirectly some kind of pistons actuated by some floating devices found on the surface of the water, in relative axial motion with respect to the fixed body of the piston. All of this devices are using the power of waves to actuate, then  directly, the generators. \n\nGood luck \nDfriend :)

No.  The electric heating element is insulated and does not conduct power into the water and surrounding metal containers.

Electrolysis. By applying electricity, you can break H2O into H2 and O2 gas.\n\n2H2O --> 2H2 + O2

Pure water, H2O is a terrible conductor of electricity, however, water that has hard water deposits and other impurities in it is a great conductor

salt water..., oh..., did you know that pure 100% water conducts no electricity at all..., but it is almost an impossible state to get it in..., even in nuclear and cogeneration plants that use high pressure dry stream.., they can only get water to maybe 3 to 5 points per billion pure..., and thats still conducts electric current..., and when it gets around 10 to 11 parts per billion..., they need to clean it again...

see the diagrams in the source\n\nBig Idea\nWater is comprised of two elements - hydrogen (H) and oxygen (O). Distilled water is pure and free of salts; thus it is a very poor conductor of electricity. By adding ordinary table salt (NaCl) to distilled water, it comes an electrolyte solution, able to conduct electricity.\n\nKey Concepts\n\n    * Ionic compounds such as salt water, conduct electricity when they dissolve in water.\n    * Ionic compounds consist of two or more ions that are held together by electrical attraction. One of the ions has a positive charge (called a cation) and the other has a negative charge (anion).\n    * Molecular compounds, such as water, are made of individual molecules that are bound together by shared electrons (i.e. covalent bonds).\n\nEssential Questions\n\n    * What happens to salt when it is dissolved in water?\n    * What are electrolytes?\n    * How can we determine the volume of dissolved ions in a water sample?\n    * How are atoms held together in an element?\n\nKnowledge and Skills\n\n    * Conduct an experiment to see that water can be split into its constituent ions through the process of electrolysis.\n    * Prepare and experiment with a 10% salt solution to better understand the process of ion exchange.\n    * Discuss and research the "softness" and "hardness" of water.\n    * Use the periodic table to identify elements and learn their characteristics.\n\nPrior Knowledge\n\n    * Define the difference between ionic and molecular compounds.\n    * Salt consists of sodium (Na) and chloride (Cl).\n    * Water is a tiny, V-shaped molecult with the molecular formula H2O.\n    * A basic understanding of how a battery works.\n    * Atoms are made of a positive nucleus surrounded by negative electrons.\n    * An atom's electron configuration, particularly the outermost electrons, determines how the atom can interact with other atoms.\n    * All matter is made up of atoms.\n    * Atoms of any element are alike, but different from atoms of other elements.\n\nCommon Preconceptions\n\n    * Students may think - "Water is a good conductor of electricity." Water is a very poor "conductor" of electricity. (The ionization constant for water is very small.) The reason it is dangerous to insert a light bulb while standing in a puddle of water is that water is a great solvent for ionic compounds. Tap water and fresh water typically contain dissolved ions in sufficient concentrations to enable the solution to be conductive. However, ions in solution carry the charge and are therefore responsible for the current, not the water itself.\n    * Students may think - "Electrons can flow through solutions." In "conduction of electricity" through solutions, electrons themselves do not pass through the solutions. Rather, the charge balance is maintained in the solution by movement of cations and anions toward the electrodes where charge transfer takes place at the solution interface.\n      Water is comprised of two elements - hydrogen (H) and oxygen (O). Distilled water is pure and free of salts; thus it is a very poor conductor of electricity. By adding ordinary table salt (NaCl) to distilled water, it comes an electrolyte solution, able to conduct electricity.\n\nConcept Map\nThis lesson and activity relates to the branch "Phases of Water" from the comprehensive Aquarius Concept Map - Water & its patterns on Earth's surface.\n\nBackground\nIn chemistry, electrolysis is a method of separating bonded elements and compounds by passing an electric current through them. An ionic compound, in this case salt, is dissolved with an appropriate solvent, such as water, so that its ions are available in the liquid. An electrical current is applied between a pair of inert electrodes immersed in the liquid. The negatively charged electrode is called the cathode, and th positively charged one the anode. Each electrode attracts ions which are of

Safe to drink... or safe to be around in the presence of an electrical current?\n\nWell zero conductivity would be ideal, because it would be evidence of zero ion presence in the water.\n\nHowever the water could be very conductive and still be "safe" to consume. Salt (Na-Cl) for instance mixed into the water would make turn the water into an ionic solution. It is therefore now has conductivity. But as we all know... we can consume salt water "safely" if it is consumed at appropriate amounts.

A water molecule contains two elements: hydrogen and oxygen. Both elements have different electronegativities, which is a fancy word meaning how well they can attract electrons. Since oxygen has a higher electronegativity, it forces the electrons of the water molecule toward itself, giving the oxygen element a slight negative charge and the hydrogen atoms slight positive charges.\nBasically speaking, water itself is somewhat charged. This makes water what is called a polar molecule and allows it to conduct electricity. This also accounts for how well water adheres to itself (cohesion).\nHowever, this polarity is relatively small.

That's a big no.  The same chemical properties that make it so oil and water don't mix makes it so oil cannot conduct electricity...ever!  In fact, to make it do so you'd have to change it's composition so completely it wouldn't really be oil anymore! :-P

Water is not a good conductor of electric current it conducts electric current because of the impurities present in it.\n\nWhy?\n\nWith this simple experiment you can verify that the distilled water presents a very low conductivity because the potential of the first circuit is much less than the developed by the battery. The small potential of this circuit is due to the presence of the H+ and OH- ions produced when some molecules of water are dissociated. However, the number of molecules of water that are dissociated is practically negligible, making the distilled water a weak electrons conductor. It is worth noting, that as the distance among electrodes increases, the resistance to the electrons transfer in the distilled water increases considerably. This fact evidences even more the low conductivity of the distilled water.\n\nWhen salt is added (NaCl) to the system, the conductivity of the system increases considerably. The water not only dissolves the salt, as well as it dissociates the salt molecule. The elementary sodium (Na) presents an excess electron and the chloride (Cl) has a strong affinity for electrons. Consequently, after dissociation, the sodium loses an electron to the chloride, forming Cl- and Na+ ions. The presence of these ions increases the conductivity of the water considerably. The positive ions (Na+) migrate to the negative electrode (linked to the pole - of the battery) and the negatives (Cl-) migrate to the positive electrodes (linked to the pole + of the pile). The conductivity of the aqueous solution water/salt is proportional to the ions concentration in the solution.\nWhen you try to measure the conductivity of tap water you can verify that it has higher conductivity in comparison with distilled water because this contains ions (less pure). The tap water has higher conductivity due to the presence of the ions: Ca2+ and Mg2+. And don´t forget, try the science at home!

Apply an electric current. The hydrogen and oxygen atoms will be seperated from one another. The hydrogen atoms will be attracted to the negative pole, the oxygens will migrate to the positve poles.\n\nThey can be collected in gaseous forms if you have the poles isolated from one another.\n\nBoiling it will do nothing but convert water molecules from their liquid form to a gaseous state. The molecules will still be intact.

You can perform electrolysis of water (or electrolysis of dilute sulphuric acid as it is called). The apparatus used is a Hoffman's voltmeter, with platinum electrodes. On passing an electric current, H+ and OH- ions in the water molecule dissociate and migrate to the corresponding electrodes.\n\nAt cathode: H+  + e- --------> H(g)\nH(g) + H(g) --------> H2(g)\n\n2 volumes of hydrogen are released at cathode.\n\nAt anode: OH- (aq) -----------> OH(g) + e-\nOH(g) + OH(g) -----------> H2O + O(g)\nO(g) + O(g) -------------> O2(g)\n\n1 volume of oxygen released at anode\nThus hydrogen and oxygen are released at a ratio of 2:1
