Vedclass · Answer

(A) Very dilute $HNO_3$ (approximately $1\%$ concentration) reacts with $Mg$ and $Mn$ to liberate $H_2$ gas.The reaction is: $Mg(s) + 2HNO_3(aq) 	o Mg(NO_3)_2(aq) + H_2(g) \uparrow$.$Al$ and $Fe$ become passive due to the formation of an oxide layer,and $Cu$ does not react with dilute $HNO_3$ to produce $H_2$ because $HNO_3$ is an oxidizing agent.
