Generally when metals are treated with mineral acids, hydrogen gas is liberated but when metals are treated with HNO3 hydrogen gas is not liberated,why?

Answer»

Thanks for asking the question.

Here's your answer

Generally when metals are TREATED with acids they give RISE to hydrogen gas. But HNO3(nitric acid) is a strong oxidising agent which no metal has the ability to displace hydrogen from it.


I Hope this answer helps you.
