How do Ca and H2SO4 react together? - Quora

It depends on the thickness of your H2SO4. If the H2SO4 is not that thick, Ca will react with hydrone first and Ca(OH)2 will come into being with lots of heat released. The chemical equation is as follow. 2H2O + Ca →Ca(OH)2 + H2↑ But as we know, Ca(OH)2 is a kind of alkali, while H2SO4 is a kind of acid.
