calcium bicarbonate

Chemical Properties

Calcium bicarbonate is obtained by dissolving calcium carbonate in carbon dioxide aqueous solution, easily soluble in water, unstable, and decomposed by heating to form stalactite or scale.

Uses

It can be used as calcium fortifier, emulsion stabilizer, dough conditioner, nutritional supplement, buffer, bulking agent, surface improver, emulsifier, curing agent, antioxidant synergist, and stabilizer.

Synthesis

When calcium carbonate encounters carbon dioxide and water, chemical attack occurs, resulting in soluble calcium bicarbonate:
CaCO3+CO2+H2O=Ca(HCO3)2
