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, qucrose, 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.

A)
Cations and anions are formed when ionic compounds dissolve in water.
B)
C)
Sucrose molecules are too large to conduct electricity in once dissolved in
water
Sucrose and other covalently bonded molecules are non-electrolytes: they
do not separate into ions in solution.
Salts, like NaCl, have ionic bonds and are considered to be electrolytes:
when dissolved in water, salts dissociate and form ions.
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
