Calcium Chloride 3V Tech. Calcium chloride production process basically consists of limestone reaction with hydrochloric acid. It can be also produced as byproduct from Solvay process for soda ash and, only in the, by the concentration and purification of naturally occurring brines from salt lakes and salt deposits.

Table 1. Carbon dioxide reacts with water to form carbonic acid (Equation 1). Carbonic acid then dissociates to give the hydrogen ion (H +) and the hydrogen carbonate ion (HCO 3 ) (Equation 2). The ability of H 2 CO 3 to deliver H + is what classifies this molecule as an .

Today we consider the chemistry of calcium carbonate, the main component of limestone rocks. Actually, limestone usually contains a mixture of calcium carbonate and magnesium carbonate, which is called dolomitic limestone. For today, however, we will ignore that fact and assume our limestone contains only calcium carbonate.

It is almost pure calcium carbonate. Calcitic limestone contains 3638% calcium and can safely be fed free choice (ad lib) mixed with salt. Dolomitic limestone contains at least 5 % magnesium carbonate and should not be used for poultry, but it is as good as calcitic limestone for other animals.
