We’re being asked to determine the solute particles present in aqueous solutions of each of the given compound. Recall that:

• Strong electrolytes: dissociate completely in water; include soluble ionic salts, strong acids, and bases

• Weak electrolytes: doesn’t dissociate completely in water; include weak acids and bases

• Nonelectrolytes: doesn’t dissociate at all; include molecular compounds
