Electrolytes Electrolytes are substances that produce ions in water. Most ionic compounds break apart into ions in water and are therefore electrolytes. Covalently bonded compounds do not usually dissociate (break apart) in water and are nonelectrolytes. Write a balanced equation for the dissociation of the following ionic compounds. EXAMPLE: CaCl - Ca?"(aq) + 2 Cl(aq) 1. BaSO4 2. NaCl 3. KOH 4. MgCl2 Note that some of the ionic compounds above produce more than one mole of anion or cation...
