Frequently Asked Questions About Precipitated Calcium Carbonate

What is Precipitated Calcium Carbonate used for in laboratories?

Precipitated Calcium Carbonate is used in suitable inorganic chemistry experiments, carbonate reaction studies, precipitation investigations, and selected materials research. It can help demonstrate acid–carbonate reactions and support studies of calcium-containing compounds. Its suitability for quantitative analysis depends on the specified grade and the requirements of the analytical method.

What are the chemical formula and molecular weight of Precipitated Calcium Carbonate?

Precipitated Calcium Carbonate has the molecular and empirical formula CaCO₃ and a molecular weight of approximately 100.09 g/mol. These values identify calcium carbonate regardless of whether it is produced by precipitation or obtained from a natural mineral source. Particle size and morphology can differ between products.

What is the CAS number of Precipitated Calcium Carbonate?

The CAS Registry Number for calcium carbonate is 471-34-1. This identifier applies to calcium carbonate, including precipitated material, when the substance is correctly identified as CaCO₃. Confirm the product specifications when particle characteristics, impurities, or specialised material properties are important to the intended laboratory procedure.

How does Precipitated Calcium Carbonate differ from ordinary Calcium Carbonate?

Both materials have the same chemical formula, CaCO₃. Precipitated Calcium Carbonate is manufactured through controlled precipitation, whereas other forms may be obtained by grinding naturally occurring minerals. Their particle size, morphology, surface characteristics, and purity can differ, affecting their suitability for particular analytical or materials research applications.

How should Precipitated Calcium Carbonate be stored and handled?

Store the material in a tightly closed, compatible container in a dry, well-ventilated area. Avoid generating or inhaling dust, and use suitable eye protection and gloves when handling the powder. Follow the applicable Safety Data Sheet for product-specific precautions, spill management, and disposal requirements.

Storage Conditions for Precipitated Calcium Carbonate

Store Precipitated Calcium Carbonate in a tightly closed, compatible container in a cool, dry, well-ventilated area. Protect the powder from contamination and excessive moisture, and keep the container clearly labelled. Avoid storage conditions that promote dust dispersion. Follow the applicable Safety Data Sheet and institutional chemical storage procedures.

Precautions for Handling Precipitated Calcium Carbonate

Review the applicable Safety Data Sheet before use. Avoid generating or inhaling airborne dust and prevent unnecessary contact with the eyes. Wear suitable laboratory gloves, protective clothing, and safety glasses, and use appropriate ventilation when weighing or transferring the powder. Clean spills using methods that minimise dust dispersion, and dispose of residues according to institutional procedures and applicable requirements.
