Dilute acids react with active metals like Zinc and Magnesium to liberate hydrogen gas and form their corresponding salts
SOME OF THE COMMON EXAMPLES ARE:-
Zinc(Zn)+2HCL(Dilute hydrochloric acid)----------------->ZnCl₂(Zinc chloride)+H₂(Hydrogen)
Magnesium(Mg)+H₂SO₄(Dilute sulphuric acid)---------------->MgSO₄(Magnesium sulphate)+H₂(Hydrogen)
