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...

water is Di pole material which means that it has some polarity due to partial charge distribution between oxygen and hydrogen . \n\nsince it is a di pole , it is divided into ions as \n\nH2O = OH-   + H+\n\nor it accepts an H+ and becomes  H20 + H+   = H3O+  \n\nso it seems like ions are the main thing to carry electrical current . so water can curry current providing a power source \n\n\nPURE WATER CANNOT HOWEVER CARRY ELECTRICAL CURRENT

Who told you that Mercury is bad conductor of heat and electricity?\n\nWe use mercury in thermometers because it is good conductor of heat and expands well.\n\nWe use mercury in large transformer switches because it is good conductor of electricity and reduces the chance of sparks.

If I remember right, the crystalline structure of the salt breaks down, and the Na and Cl ions move freely in the water, dissolving into the water.\nSince the salt breaks down into free ions, that explains why salt water is such a good electrical conductor.

Pure water is a poor conductor but when you have water on a surface, you basically have an electrolyte solution that allows electricity to flow much easier.

Why dont you just try going to google search and just type "NaCl Electrodialization". You should get more info. than you think you'ld get.

Salt (or more specifically, Sodium Chloride salt) is a strong electrolyte, meaning that when dissolved in water it will completely break up into ions (Na+ and Cl- ions).\n\nPure water, by itself, does not conduct electricity, but when you dissolve an electrolyte in it, an electric current can pass through the solution.\n\nIn order for a electric current to flow there must be charge carriers which can move.  Pure water does not have these charge carriers, but after a salt is dissolved and ions are present in solution, the solution becomes conductive.

To the first answer----WHAT? What does hydrogen bonds have to do with polarity? Ever heard of dipoles? Why do the need hydrogen bonds when the electronegativity is what is causing the polarity? Please, don't answer question you have no idea about. Anyone can look up stuff and copy and paste. NaCl  doesn't form hydrogen bonds but is VERY solube.\n\nNow, to answer the question. I think what you are eluding to by using "most," is the majority of them. What it boils down to is the molecule is too big. If you have like CH3-Cl, it is a small molecule and the polarity is spread of a small place, thus making it polar. Now, if you have something like C-C-C-C-C-C-C-C-C-C-Cl, the only part that is polar is the Cl part and the rest of the molecule is not, thus will not interact in water.

This is because acids dissociate in water, for example:\nHCl becomes    (H+)   +  (Cl-),\nH2SO4 becomes  2(H+)  + (SO4--),\nforming (+) ions, like (H+), and (-) ions, like (Cl-) or (SO4--),\nwhich also are called as kations and anions.\n\nThese are charged particles which move in water as independent particles, and also they move in electric field forced by the electric field, and thus carrying the charge. Electric current is movement of electrically charged particles.\n\nThe same effect will be with salts which can dissociate in water

u know that ice is H20 right? but that's not enough. it would easily melt if that's pure ice. so there is a Salt there. NaCl. why? because water or an ice slowly melts when thre is a substance. and vice versa when the water boils with salt.

Salt water works better because it's a better conductor of electricity as opposed to just tap water.  In salt water, you have a solution of both Cl- and Na+ floating about creating a means of transferring electricity (electolytes).  So, instead of a saltbridge to provide the transfer of ions, all the ions needed are right there, which will quickly drain the battery.  Think of it as a short circuit - you have a large current because the path of resistance from the cathode to the anode is nothing.  Plus, there's plenty of ions to provide that means of conduction.

Table salt doesn't get affected at all chemically.\n\nAnd it doesn't raises the boiling point, it lowers it!!!

It depends.\nThe salt has to dissolve in water.\nThe more ions / cm3 in te water (never mind the kind),\nthe better the electric conductivity.

Yes, of course "salt" (table salt) can dissolve in water.\n\nThereare, however, many types of salts.  "Salt" is a general term refering to an ionic compound formed with a metal cation (+) and a non-metal anion (-), but it has come to commonly refer to table salt [NaCl] by most common people.\nSince salts are ionic compounds, they are soluble in water.  Some salts are very soluble, others only slightly, others are almost totally insoluuble.\nSodium Chloride (NaCl) is very soluble, but other salts like Silver Chloride (AgCl) are almost totally insoluble.\n\nHave you ever heard of the "like dissolves like" rule?  It states that polar solvents (like water) can dissolve ionic or polar solutes (like salt).  Non-polar solvents will dissolve non-polar solutes.\nThe polar water molecules will surround the Ions making up the salt, breaking it up into ions and placing it in solution.\n\nWhen you dissolve table salt in water, it forms an aqueous solution of Na+ and Cl- ions.\nSince the Na+ ion has a positive charge, it is surrounded by the Oxygen end of a water molecule which has a slight negaitve charge due to the two lone pairs of electrons surrounding it and the difference in electronegativity between the Oxygen and the Hydrogen atoms.  Since the Chloride ion has a negative charge, it is surrounded by the Hydrogen side of the water molecule.\n\n\n"corrupted_bunny" doesnt know what she is talking about.  Table salt very much so dissolves in water.  Melting is a completely different process than dissolving.

Sodium bicarbonate in solid form is a poor conductor.    However, it will ionize when dissolved in water and conduct electricity then.

Hmmm...\n\nIn order to clarify any possible ambiguities, I will attempt to answer this question from 2 very different perspectives.\n\nGiven this came from your anatomy homework:  Water carries a current because H2O readily dissociates into H+ and OH- ions.  The charged ions make water a good electron carrier, and therefore, a good conductor for current.\n\nIn case this came from another science class: Water carries a current because it is subject to physical forces such as atmospheric phenomenae, namely wind, the gravitic pull of the moon (the source of tides), the spinning of the earth, the creatures which inhabit it.... and basically anything which causes water to move.  All these forces sum up to give water the various currents we see in different parts of the world.

Althouigh I am sure you mean Sodium Chloride when you say "Salt", just to be perfectly clear....there are multiple types of "salt".\nA salt is an ionic compound made up of a matal cation and a non-metal anion. Sodium Chloride ("table salt") is an example of a salt, so is Potassium Chloride and Ammonium Nitrate.\n\nWhen you dissolve a salt in water, the freezing point of the solution is lowered.  Likewise, when dissolving a salt, the boiling point of the solution is raised.\n\nBut you asked about a temperature change.\nWhen dissolving some salts, the dissolving process is endothermic...meaning that it requires enegry input to proceed.  When a endothermic process occurs, the temperature of the surroundings (this case, the water) drops.\nThere are also salts which give off energy when they are dissolved in water.  Processes which give off excess energy are called exothermic and can raise the temperature of the surroundings.\nThere are also a few (not too many) "ideal" salts which neither take in or give off energy when they dissolve.\n\nWhen the salt dissolves, if the "product" (the aqueous salt) has a lower enthalpy than the undissolved salt, the solution is said to be exothermic.  If the enthalpy increases, the solution is said to be endothermic.\n\nSalts like Potassium Chloride, Ammonium Nitrate, and several others (probably NaCl too, which you refered to) are endothermic when dissolved in water, and thus, when dissolved cause the temperature of the solution to decrease slighty.\n\nSalts like Sodium or Potassium Hydroxide are great examples of salts which are exothermic (give off energy) when they are dissolved in water.  When dissolving these salts in water, a notible increase in temperature can be observed.
