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

A

zinc acts as oxidising agent when reacts with `HNO_(3)`

B

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

C

in electrochemical series zinc is above hydrogen

D

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

Text Solution

Verified by Experts

The correct Answer is:
D
`NO_(3)^(-)` is reduced in preference to `H_(3)O^(+)`.

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

Assertion: Zn gives H_(2) gas with dil. HCl and also with dil. H_(2)SO_(4) . Reason : In different medium, change in oxidation number shown by mangnese is altogether different.

In the permanganate titration, the solution of reductant is always made acidic by adding H_(2)So_(4) rather than HCl or HNO_(3) because :
