Question

why some metals do not react with nitro acid to release hydrogen gas​

Answer 1

Explanation:

Hydrogen gas is not evolved when metals react with_______

Answer:

Hydrogen gas is not evolved when a metal reacts with nitric acid because nitric acid is a strong oxidizing agent; it oxidizes the hydrogen to produce water.

When a metal reacts with nitric acid, no hydrogen gas is produced. It’s because HNO3 is a strong oxidizer.

It reduces itself to any of the nitrogen oxides (N2O, NO, NO2) after oxidizing the H2 released to water.

Magnesium (Mg) and manganese (Mn), on the other hand, react with very dilute HNO3 to produce H2 gas.
