When salts dissolve in water, they dissociate into cations and anions which may undergo hydrolysis with water. In general, metal ions undergo hydrolysis to produce hydronium ion when the metal is a transition metal with a 2+ charge or higher, or a non-transition metal with a 3+ charge or higher. Which of the following salts should produce an acidic solution when dissolved in water? Select all that apply. There may be more than one correct answer. A. MgCl2 ...
