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

`NO_(3)^(-)` ions is reduced in preference to hydronium ion

B

Conc. `HNO_(3)` is a weaker acid than conc. `H_(2)SO_(4)` and conc `HCl`

C

Conc. `HNO_(3)` acts as a reducing agent

D

Zinc is more reactive than hydrogen

Text Solution

Verified by Experts

The correct Answer is:
A
`Zn + H_(2)SO_(4) rarr ZnSO_(4) + H_(2)`
`Zn + conc. 2HCl rarr ZnCl_(2) + H_(2)`
`Zn + 4HNO_(3) rarr Zn(NO_(3))_(2) + 2NO_(2) + 2H_(2)O`
