Although Fe is placed above hydrogen in ...

Although Fe is placed above hydrogen in the electrochemical series, dihydrogen in not obtained by its reaction with nitric acid. Explain with reasons.

Text Solution

Verified by Experts

`HNO_(3)` being a strong oxidising agent oxidises dihydrogen into water and itself gets reduced to nitrogen dioxide, Fe + 6HN`O_(3) rarr "Fe"(NO_(3))_(3) + 3NO_(2) + 3H_(2)O`
