Calcium Bicarbonate – 500 gram Packs

Calcium Bicarbonate, also known as calcium hydrogen carbonate, is an inorganic compound represented by the formula Ca(HCO₃)₂. It forms in aqueous systems when calcium carbonate interacts with dissolved carbon dioxide and water. Unlike many conventional laboratory salts, calcium bicarbonate is not ordinarily isolated as a stable, pure solid under ambient conditions and is generally encountered in solution. Its chemistry is relevant to water hardness, carbonate equilibria, dissolved inorganic carbon, and the formation of calcium carbonate precipitates. These characteristics make it a useful subject for appropriately designed educational experiments and research involving aqueous chemical systems. For this 500 gram product listing, the actual supplied form and concentration must be confirmed before finalising product-specific specifications. Laboratories should verify the material identity and follow applicable technical documentation and chemical handling procedures.

Why Choose Lab Wale to Buy Calcium Bicarbonate

Lab Wale offers a sourcing option for laboratory chemicals and scientific supplies used by schools, colleges, universities, research centres, and laboratory professionals. When considering Calcium Bicarbonate in a 500 gram pack, buyers should confirm the chemical identity, supplied physical form, concentration, applicable grade, and available technical and safety information. These details are important because calcium bicarbonate is generally encountered in aqueous solution rather than as a stable, pure dry solid. Reviewing product specifications helps laboratories assess suitability for their intended procedures.

Frequently Asked Questions About Calcium Bicarbonate

What is Calcium Bicarbonate?

Calcium bicarbonate, also called calcium hydrogen carbonate, is an inorganic compound represented by Ca(HCO₃)₂. It is generally present in aqueous solution and is associated with dissolved calcium and bicarbonate in natural water systems. Its chemistry is important in studies of water hardness and carbonate equilibria.

What are the chemical formula and molecular weight of Calcium Bicarbonate?

The nominal formula is Ca(HCO₃)₂, and its calculated formula mass is approximately 162.11 g/mol. Its empirical formula is CaH₂C₂O₆. These values describe the compound’s nominal composition and should not be interpreted as the molecular weight or concentration of an aqueous commercial preparation.

Why is Calcium Bicarbonate generally encountered in solution?

Calcium bicarbonate is not ordinarily isolated as a stable, pure solid under ambient conditions. It forms in water when calcium carbonate interacts with dissolved carbon dioxide. Changes in temperature or carbon dioxide concentration can shift the equilibrium and promote the precipitation of calcium carbonate.

What are the laboratory applications of Calcium Bicarbonate?

Its chemistry is relevant to water hardness experiments, carbonate equilibrium studies, calcium carbonate precipitation, and investigations of dissolved inorganic carbon. The suitability of a supplied preparation depends on its concentration, composition, and the requirements of the experimental method.

How should Calcium Bicarbonate be stored and handled?

Storage conditions depend on the actual supplied formulation and concentration. For an aqueous preparation, use a compatible, securely closed container and follow the supplier’s storage instructions to minimise contamination and changes in composition. Review the applicable Safety Data Sheet and follow institutional handling and disposal procedures.

Storage Conditions for Calcium Bicarbonate

Storage requirements should be established for the actual supplied formulation. If provided as an aqueous preparation, keep it in a compatible, securely closed, clearly labelled container under the temperature conditions specified in its technical documentation. Avoid contamination and unnecessary changes in temperature or carbon dioxide exposure that could affect solution equilibrium. Follow the applicable Safety Data Sheet and institutional storage procedures.

Precautions for Handling Calcium Bicarbonate

Confirm the product’s physical form and concentration before use, and review the applicable Safety Data Sheet. Wear suitable laboratory clothing, gloves, and eye protection, and avoid contamination during handling. Use clean, compatible equipment and follow the experimental procedure when controlling pH or carbon dioxide exposure. Manage spills and dispose of laboratory residues according to institutional requirements and applicable environmental regulations.
