Vedclass · Answer

(B) Most metals react with dilute $HNO_3$ to produce nitrogen oxides instead of hydrogen gas because $HNO_3$ is a strong oxidizing agent.However,very dilute $HNO_3$ (approx. $1\%$ concentration) reacts with very reactive metals like $Mn$ and $Mg$ to evolve hydrogen gas.The reaction is: $Mn(s) + 2HNO_3(dil.) 	o Mn(NO_3)_2(aq) + H_2(g)$.

Hydrogen gas is evolved by the action of cold dilute $HNO_3$ on which of the following metals?
