Select the two true statements that describe solutions of ionic compounds, such as NaCl an CuCl2. Ionic compounds DO NOT ionize or electrolyze in solution. They remain connected as molecules. Solutions of ionic compounds will conduct an electrical current and are called electrolytes. Solutions of ionic compounds WILL NOT conduct an electrical current and are called non-electrolytes. Ionic compounds will dissociate or electrolyze in aqueous solution.
