Homework Answers
1. NaCN + H2O -------------------> NaOH + HCN
NaOH is strong base while HCN, is a weak acid, as a result solution will be basic and pH be greater than 7
2. KClO + H2O -------------------> KOH + HClO
KOH is strong base while HClO, is a weak acid, as a result solution will be basic and pH be greater than 7
3. CaCl2 + 2H2O -------------------> Ca(OH)2 + 2HCl
Ca(OH)2 is strong base while HCl, is a strong acid, as a result solution will tend to be neutral and pH equal to 7
4. NH4Br + H2O -------------------> NH4OH + HBr
NH4OH is weak base while HBr, is a strong acid, as a result solution will be acidic and pH be less than 7

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 ...
