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.

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!

It's soluble because in water it dissociates into the sodium cation and benzoate anion,  as someone else stated it's an ionic compound, so  the extent of its solubility depends on the degree of ionisation/dissociation, which is predominantly an aqueous event

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!

A concentrated solution has more sugar and is more conductive.

1. VERY PURE water is a poor conductor of electricity. However, very small \namounts of impurities, especially salts, greatly increase the electrical\nconductivity of water.\n2. The main carriers of electrical current are dissolved ions. If a \nbattery is connected to a container of water so that\nthe (+) and (-) poles of the battery are immersed in the water, the\npositive ions will migrate toward the (-) pole and the negative ions will\nmigrate 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 \nless, depending upon their electrical charge and their size. More highly charged, \nsmaller ions are more efficient carriers of the electrical current.\n4. The higher the concentration of ions, the greater is the conductance of \nthe solution.\n5. There is a complication however, the water and / or certain of the ions \nmay undergo a chemical reaction to one or the other, or both of the electrodes.\nYou 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 \nare as mobile as "free" electrons in a metal are. And the differences are very\nlarge. For example, if the conductivity of  VERY PURE WATER is 0.000004\nconductivity units, the conductivity of a saturated solution of common\ntable salt NaCl is 23 conductivity units, and the conductivity of a typical\nmetal 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\nvery slow and sluggish moving. \nCompletely demineralized water actually does not conduct electricity, and is\nwidely used as a coolant in high powered radio amplifiers.  However, when\nexposed to even small amounts of impurities, (even normal air), It becomes a\nfair conductor.  It is not the water conducting this electricity so much as\nthe dissolved minerals in it.  Some of these minerals are decent insulators\nthemselves, but when dissolved in water still allow conduction because the\nmolecules are now free to move around.\nIn ionic liquids these electrons remain \nstuck to big, round atoms,\nand these atoms do the swimming around, relatively slowly, dragged by \ntheir electric charge.\nSort of a ball and chain thing.\nElectrons in metal are "free"; they slip rather freely across all the \natoms, and do not need to drag one around with them.\nSo, carrier mobilities in ionic liquids are some orders of magnitude lower \nthan carrier mobilities in metals.\nSo their resistance is higher.\nIf you had a snail-trail of salt-water or molten salt with the same length \nand cross-section as a metal wire,\nit would use up half the voltage and get hot trying to pass one tenth the \ncurrent the wire can handle.\nIn a metal, each metal atom contributes about one mobile electron that \nhelps the current flow.\nIn molten salts like NaCl, every atom has a + or - charge and contributes \nto the current flow.\nSo there are just as many carriers per unit volume as in a metal.\nBut in water-solutions of salts, the salt is a minority.\nUsually less than 10%  of the solution is ions, so that makes the \nconductivity even poorer.\nThat is part of why we will never make our power lines out of seawater in \npipes.

It comes from the combination of "electric" and "-on," such as in anion, cation, and ion. It is electric, because it is the carrier of electric current through solid bodies.

An ionic compound is dissolved with an appropriate solvent, or otherwise melted by heat, 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 the positively charged one the anode. Each electrode attracts ions which are of the opposite charge. Therefore, positively charged ions (called cations) move towards the cathode, while negatively charged ions (termed anions) move toward the anode. The energy required to separate the ions, and cause them to gather at the respective electrodes, is provided by an electrical power supply. At the probes, electrons are absorbed or released by the ions, forming a collection of the desired element or compound.

solute is the substance that dissolves into the solvent. i.e. in salt and water, salt would be the solute and water would be the solvent.

Pure water is *not* a good conductor of electricity.  Dissolved ions are necessary to conduct electricity and at room temperature, there is only 10^-7 mol/L of H+ and OH- in pure water.\n\nDissolving salts (including strong acids) in water greatly increases the conductivity of the solution.\n\nTap water is a modest conductor of electricity because of dissolved ionic minerals and impurities.\n\nHeating water increases its dissociation constant making more H+ and OH- available in solution.

When salt  ( NaCl ) dissolves in water, it becomes Na+ and Cl-, or, atoms called "ions".  It's these ions that carry the electrical charge.  The higher the concentration of these ions, the more conductive the solution will be.
