Identify the basic salt from the following salts:
(a) Na 2 CO 3
(b) NH 4 Cl
(c) NaNO 3
(d) KCl
Ans.
Salts can also be acid basic and neutral
Here
- Na 2 CO 3 : It is made up of a strong base (NaOH- sodium hydroxide) and weak acid (H 2 CO 3 - carbonic acid). Hence, it is a basic salt .
- NH 4 Cl : It is made up of a weak base (NH 4 OH- ammonium hydroxide) and strong acid (HCl - hydrochloric acid). Hence, it is acidic in nature.
- NaNO 3 : It is made up of a strong acid (HNO 3 - nitric acid) and strong base (NaOH - sodium hydroxide) so it is neutral in nature.
- KCl : it is also made up of strong acid (HCl- hydrochloric acid) and strong base (KOH - potassium hydroxide) and hence is neutral in nature.
So, the correct option is (a) Na 2 CO 3
