Which one of the following salts will form an acidic solution on dissolving in water? NH4I...
Homework Answers
Ans: NH4I,
When NH4I is dissolved in water,it undergo following hydrolysis reaction:
NH4I+H2O→NH4OH+H++I-
NH4OH is a very weak base,remains almost undissociated in aq. soln, whereas HI is a strong acid, remains almost wholly ionised as H++I- thus providing acidity to the water.
