Question

Correct the statement:Very dilute nitric acid reacts with zinc to produce hydrogen

Answer 1

Hello there!

Do you know?

Dilute acids, when react with active metals (above Hydrogen), produce hydrogen gas and a metal salt.

However, nitric acid is an exception in this case because of its strong oxidizing nature.

As it is strongly oxidising substance, the hydrogen formed (when it reacts with an active metal) gets oxidized to water, and hence no hydrogen evolves.

However, when very dilute nitric acid reacts with metals like Magnesium and Manganese, hydrogen gas is liberated.

So, you got your answer!

Instead of zinc, there should be Manganese (Mn) or Magnesium (Mg).

THANKS!
