Usage

Description

Calcium bicarbonate, also known as calcium hydrogen carbonate, is a chemical compound derived from the reaction of calcium carbonate with carbon dioxide in an aqueous solution. It is easily soluble in water, exhibits instability, and decomposes upon heating to form stalactite or scale.

Uses

Used in Food Industry:
Calcium bicarbonate is used as a calcium fortifier to enhance the nutritional value of various food products. It acts as an emulsion stabilizer, helping to maintain the consistency and texture of emulsified products. As a dough conditioner, it improves the quality and workability of dough in the baking process. Additionally, it serves as a nutritional supplement, providing an essential mineral to the diet.
Used in Pharmaceutical Industry:
In the pharmaceutical sector, calcium bicarbonate is utilized as a buffer to maintain a stable pH environment for various medications. It also functions as a bulking agent, contributing to the volume and consistency of tablets and capsules.
Used in Cosmetics Industry:
Calcium bicarbonate is employed as a surface improver in the cosmetics industry, enhancing the texture and appearance of skincare and beauty products. It also acts as an emulsifier, promoting the mixing of oil and water-based ingredients in cosmetic formulations.
Used in Chemical Industry:
In the chemical industry, calcium bicarbonate is used as a curing agent in the production of certain materials, facilitating the hardening or setting process. It also serves as an antioxidant synergist, working in conjunction with other antioxidants to improve the stability and shelf life of products.
Used in Water Treatment:
Calcium bicarbonate is used as a stabilizer in water treatment processes, helping to maintain the balance of minerals and preventing the formation of unwanted deposits or scale buildup.

Synthesis

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