Which metals form hydrogen gas on reaction with very dilute nitric acid ? Write the equation of the reaction.

Answer»

Solution : Magnesium (Mg) and manganese (MN) REACTS with very DILUTE nitric ACID and form hydrogen gas.
`Mg(s)UNDERSET("very dilute")(2HNO_3) to Mg(NO_3)_2 + H_2`
`Mn(s) + underset("very dilute")(2HNO_3) to Mn(NO_3)_2 + H_2`
