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
