2. A plant makes liquid CO 2 by treating dolomitic limestone with commercial sulfuric acid by the reactions: CaCO 3 + H 2 SO 4 → CaSO 4 + CO 2 + H 2 O MBCO 3 + H 2 SO 4 → MgSO 4 + CO 2 + H 2 O The dolomitic limestone contains 68% CaCO 3, 30% MgCO 3 and 2% SiO 2, an inert in the reactions.
dolomitic limestone is known to be slower (Lindsay, 1979; Rippy et al, 2007). Recent field experiments in Iowa also showed that the time to reach a certain pH value was longer for dolomitic lime and that sometimes the maximum pH reached also was lower (Pagani and Mallarino, 2012).

Dolomite, CaCO 3.MgCO 3, (calcium magnesium carbonate), is also called, dolomitic limestone, magnesian limestone or dolostone. It is the result of a partial or full dolomitization of calcium carbonate. Dolomite is quarried, crushed and ground to the appropriate fractions. Some applications of dolomite include agriculture, refractories, because ...
