Calcium Carbonate
Calcium Carbonate occurs as a fine, white or colorless, microcrystalline powder. It is stable in air, and it is practically insoluble in water and in alcohol. The presence of any ammonium salt or carbon dioxide increases its solubility in water, but the presence of any alkali hydroxide reduces the solubility.
Magnesium Carbonate
Magnesium Carbonate occurs as light, white, friable masses, or as a bulky, white powder. It is a basic hydrated magnesium carbonate or a normal hydrated magnesium carbonate. It is stable in air. It is practically insoluble in water, to which, however, it imparts a slightly alkaline reaction. It is insoluble in alcohol, but dissolves, with effervescence, in dilute acids.
Calcium Chloride
Calcium Chloride occurs as white, hard fragments, granules, or powder. It is anhydrous or contains two molecules of water of hydration. It is deliquescent. It is soluble in water and slightly soluble in alcohol. The pH of a 1:20 aqueous solution is between 4.5 and 11.0.
Magnesium Chloride
Magnesium Chloride occurs as colorless flakes or crystals. It contains six molecules of water of hydration. It is hygroscopic, very soluble in water, and freely soluble in alcohol.
Ferric Sulphate
Ferric sulphate is a very hygroscopic, white to yellowish powder which decomposes in air. Slowly soluble in water. Slightly soluble in alcohol. It should be stored protected from light.
Zinc Sulphate
Zinc Sulphate is a white crystal or powder, easily soluble in water, solution is acidic, slightly soluble in alcohol and glycerin.
Sodium Ferric Pyrophosphate
Sodium Ferric Pyrophosphate occurs as a white to tan powder. It is insoluble in water, but is soluble in hydrochloric acid.
Calcium Citrate
Calcium Citrate occurs as a fine, white powder. It is very slightly soluble in water, but it is insoluble in alcohol.
Magnesium Citrate
Magnesium Citrate is white or almost white, fine powder. Sparingly soluble in water, practically insoluble in ethanol. It dissolves in dilute hydrochloric acid.
Potassium Citrate
Potassium Citrate occurs as transparent crystals or as a white, granular powder. It is deliquescent when exposed to moist air. One gram dissolves in about 0.5 mL of water. It is almost insoluble in alcohol.
Manganese Citrate
Manganese Citrate occurs as a light pink or pink-white, fine, granular solid. It is very slightly soluble in water.
