Zn gives H(2) gas with H(2)SO(4) and HCl...

`Zn` gives `H_(2)` gas with `H_(2)SO_(4)` and `HCl` but not with `HNO_(3)` because

A

Zn Acts as oxidising agent when reacts with `HNO_3`

B

`HNO_3` is weaker acid than `H_2SO_4` and HCl

C

Zn is above the hydrogen in electrochemical series .

D

`NO_3^(-)` is reduced in preference to `H^+` ion.

Text Solution

Verified by Experts

The correct Answer is:
D
Due to reduction of `NO_3^-` in preference to `H^+` ion. `H^+` ion is not reduced to give `H_2` gas .
