Why can't dissolved sugar conduct electricity?

The atomic bonds in sugar are very tight and do not allow for (measurable) ionization, which is what helps water conduct electricity.  Salt (NaCl) is a powerful ionization agent - the Cl atom "steals" Na's outer electron, forming a Na+ ion, which attracts new electrons introduced into the water.  We call that a conductor!

You get the first answered.\nCovalent bonds are strong and don't disassociate into ions, as ionic bonds do. Watch.\nNaCl common salt, sodium and chlorine, put in solution.\n\nNa+  and Cl- they disassociate and you can follow the path of electricity Electron jumps from sodium to be accepted by chlorine. That is electron flow; conduction of electricity.

It is a polymer made up of two different monomeres. If it is used in batteries it will likely allow ion conduction, i.e. the migration of ions through the polymer. No idea whether an additional solvent is required, though.

Common table salt has other ingredients in it including sugar. It is not close to pure.   It would take very efficient purification.

In an electrolytic cell you can plate most any metal that doesn't quickly react with the solvent and its solutes.  The force of the copper ions gaining electrons at a negative charged zinc electrode is certainly possible.\n\nSince the copper would receive two electrons and go from a +2 to a zero oxidation state, you would say that it is being reduced.

By heating it, you can change the physical property of sugar. Sugar is from the sugar cane, Have you ever try making alcohol? I think then sugar serves as a catalyst. \n\nYou are not trying to make moonshine, are you?\nShame on you.

No, because there are no ions in there.  Add some metals, or salt, or acid/base, and then it will.  In tap water, there are those, so tap water does conduct electricity.

Water will weakly (very weakly) conduct an electric current because it self-ionizes or ionizes (breaks apart) into Hydronium (H3O+) and hydroxide ions (OH-).  This isn't enough to show any conductivity with the traditional "light bulb conductivity tester."\n\nBy "water" I mean completely pure water.  Once you start dealing with water in oceans, ponds, bathtubs, etc. you've added solutes to the water.  If those solutes are able to break apart into ions (ionic and limited covalent compounds) then the water will conduct an electric current.\n\nThe question about table salt has already been answered, but if you're asking how that's different from "salt" as a chemist would use the term....  A salt is a compound made from the anion of an acid and the cation of a base... this covers most if not all ionic compounds...

wood is a bad conductor. therefore it will not conduct current. but presence of moisture(water content) will make it a good conductor. therefore, dry wood wont conduct currrent. but live plant & tree will conduct current.if current passes through the plant or tree, the wet wood of tree will provide resistance to the flow of electrons(you know that current is produced because of flow of electrons). you know that if resistance is offerred to the current, heat will be produced.\n           heat produced= (square of current)*resistance offered by the tree\n            you also know that every component has certain latent heat content. if the heat produced is more than the latent heat of the wood, tree will burn.

Ya you should cuz distilled water is not good as a conductor but adding salt to it makes it a good conductor of electricity and since soap contains alot of salts that can decompose into negative and positive charges i think ya u should worry about electric shock

(m)\n\n1. VERY PURE water is a poor conductor of electricity. However, very small amounts of impurities, especially salts, greatly increase the electrical conductivity of water.\n2. The main carriers of electrical current are dissolved ions. If a \nbattery is connected to a container of water so that the (+) and (-) poles of the battery are immersed in the water, the positive ions will migrate toward the (-) pole and the negative ions will migrate toward the (+) pole (electrical opposites attract). This closes the\n"switch" and electric current flows through the solution.\n3. Different ions can help carry the electric current, some more / some  less, depending upon their electrical charge and their size. More highly charged,  smaller ions are more efficient carriers of the electrical current.\n4. The higher the concentration of ions, the greater is the conductance of the solution.\n5. There is a complication however, the water and / or certain of the ions may undergo a chemical reaction to one or the other, or both of the electrodes. You may not want to introduce this in the beginning but it does happen.\n6. None of the ion electrical current carriers of salts dissolved in water are as mobile as "free" electrons in a metal are. And the differences are very large. For example, if the conductivity of  VERY PURE WATER is 0.000004 conductivity units, the conductivity of a saturated solution of common table salt NaCl is 23 conductivity units, and the conductivity of a typical metal such as copper wire is 60, 000, 000 conductivity units. So while the\nions in a dissolved salt behave something like "free" electrons, they are very slow and sluggish moving

Salt water can conduct electricity because there are ions in it. Na+ and Cl- from the salt.\nSee http://www.scienceaid.co.uk/salt.html for more

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

Sugar doesn't melt.  Rather, it decomposes.  It decomposes into its constituent elements, which are C, H, and O.  The H and O are given off as gases, leaving the C, carbon, left behind as a black mass in the bottom of the test tube. It's only carbon, presuming you heat it enough to drive off all of the sugar molecules.

Sugar doesn't actually melt it dissolves in water. The temperature of the water determines how quickly it is dissolved- the warmer the water, the quicker the sugar dissolves. It is a really a solution of glucose and water- not melting (if it melted it would only be the glucose).

No , coz the sugarcane is treated with lot of antiseptics and purified while producing sugar. However some amounts remain which r allowed by the Hygeinic requirement Standards
