reaction calcium carbonate and sulfuric acid to form gypsum

A model for calcium carbonate neutralization in the ...

In this paper we present a mathematical model for the reaction between calcium carbonate (CaCO 3) and a solution containing sulfuric acid (H 2SO 4). We assume that Ca2+ ions (liberated on the reaction surface) react with SO2− 4 ions to form solid gypsum crystals (CaSO 4) which, in turn, may accumulate on the reaction surface, hindering the neutralizing process
