Answer 2

Answer: HCOOH is the one which is different from all others.

Explanation: All the given above are acids. Acids can be classified as weak and strong.

Weak Acids: These acids donot dissociate completely into its ions in water solution.

Strong Acids: These acids dissociate into its ions completely in water solution.

Ionization of every acid given above are:

$HCl(aq.)\rightarrow H^+(aq.)+Cl^-(aq.)$

$HNO_3(aq.)\rightarrow H^+(aq.)+NO_3^-(aq.)$

$H_2SO_4(aq.)\rightarrow 2H^+(aq.)+SO_4^{2-}(aq.)$

$HCOOH(aq.)\rightleftharpoons H^+(aq.)+COOH^-(aq.)$

As HCOOH acid is an organic acid, hence it a weak acid and thus, it does not dissociate into its ions completely.
