What do you need to add to H2SO4 to get H2?

In order to isolate hydrogen from sulfuric acid, it is necessary to carry out a reaction of interaction of sulfuric acid with any metal. As a result of the reaction, a salt of sulfuric acid and a metal will precipitate and hydrogen will be released. For example, let’s carry out the reaction of sulfuric acid with magnesium. As a result of the reaction, magnesium sulfate is formed and hydrogen is released. The chemical equation for the reaction is as follows:

H2SO4 + Mg = MgSO4 + H2.
