Only those metals which are more reactive than hydrogen and so placed above hydrogen in the reactivity series will react with dilute acids to form metal salt and hydrogen gas. As we go down, the metals react less vigorously. In particular dilute nitric acid (< 0.5 M) does produce hydrogen with moderately reactive metals such as magnesium and zinc, even though reactions are different at higher concentrations, and with other metals. These metals react with with dilute sulfuric acid just as they did with dilute hydrochloric acid; the reaction between magnesium and dilute sulfuric is familiar to many beginning chemists. +      H2(g). Dilute sulfuric acid will, in theory, react with any metal that lies above hydrogen in the reactivity series by displacing hydrogen from the acid, releasing it as a gas and forming the sulfate salt of the metal.
