Explanation / Answer
Ans 16. b) It is weakly acidic.
Since ammonia is a weak base and perchloric acid is a strong acid , the salt formed as a result of the neutralisation reaction , will be weakly acidic .
The salts of strong acid and weak base are neutral and that of strong base and weak acid is weakly basic .
