Vedclass · Answer

(B) Very dilute $HNO_3$ (approximately $1\%$ concentration) reacts with very active metals like $Mg$ and $Mn$ to evolve hydrogen gas. The reaction is: $Mn(s) + 2HNO_3(aq) \rightarrow Mn(NO_3)_2(aq) + H_2(g)$. Other metals like $Fe$,$Cu$,and $Al$ do not evolve $H_2$ gas with dilute $HNO_3$ because $HNO_3$ is a strong oxidizing agent and oxidizes the produced $H_2$ to water.

Which of the following metals releases hydrogen gas upon reaction with cold dilute $HNO_3$?
