Water is the universal solvent and we have seen how salts, like NaCl, dissolve in water. Many other molecules dissolve in water as well: sugar is a good example. A salt solution will conduct electricity but a sugar solution will not. Let's use the sugar, sucrose, as an example that readily dissolves in water, but the solution does not conduct electricity. Compare this dissolving process of sucrose with that of NaCl to explain why one is an electrolyte and the other is not. Choose ALL that apply.

E Glucose is a carbon compound and the bonds are not readily broken by the action of a polar solvent like water. Glucose would be an electrolyte in a non-polar solvent.
