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

Options

A. Zn acts as oxidising agent when reacts with `HNO_(3)`
B. `HNO_(3)` is weaker acid than `H_(2)SO_(4) and HCl`
C. Zn is above the hydrogen in electrochemical series
D. `NO_(3)^(-)` is reduced in preference to `H^(+)` ion

Answer

D

Explanation

Due to reduction of `NO_(3)^(-)` in preference to `H^(+)` ion. `H^(+)` ion is not reduced to give `H_(2)` gas.
