CA L C I U M , the same element that causes eggshell hardness,
is one of the main components of the limestone that enables a great edifice to stand through the ages. The characteristic firmness of various calcium salts is the one property that makes these diverse substances essential to the framework of both living and inanimate things. Calcium derivatives which are an essential part of the animal skeleton and the earth 's crust, play a vital rôle in today's industries, including: ceramics, enameling, tanning, dyeing, and the manufacture of bleaches, paper, fertilizers, and medicines.
In the laboratory, as well as in industry, the application of calcium compounds demands chemicals of maximum purity and dependability. Merck & Co., Inc. for almost four generations has set the pace in the production of fine laboratory chemicals. The Merck label, which conforms to A.C.S. methods of stating maximum impurities, always has been the chemist 's assurance of uniformly high quality.
Among Important Merck Reagent Calcium Compounds:
Calcium Acetate Reagent Calcium Carbonate Reagent
Calcium Chloride Anhydrous Reagent
