Understanding Calcium Carbonate
Calcium Carbonate, a compound with the chemical formula CaCO3, is a naturally occurring mineral that plays a crucial role in various biological and industrial processes. It is primarily found in rocks, particularly in limestone, chalk, and marble, and serves as the main component of shells in marine organisms, eggs, and snails. In this article, we will explore the properties, uses, and importance of Calcium Carbonate in our daily lives.
Properties of Calcium Carbonate
Calcium Carbonate is a white, odorless solid that is insoluble in water but reacts vigorously with acids, producing carbon dioxide gas. Its chemical properties make it a versatile substance in various fields. Here are some important properties:
- Molecular Weight: The molecular weight of Calcium Carbonate is approximately 100.09 g/mol.
- Solubility: It is sparingly soluble in water but soluble in acidic solutions.
- Thermal Stability: Calcium Carbonate decomposes upon heating to form Calcium Oxide (CaO) and Carbon Dioxide (CO2). The reaction can be expressed as:
CaCO3 (s) ‚Üí CaO (s) + CO2 (g)
These properties make Calcium Carbonate useful in a variety of applications, from dietary supplements to construction materials.
Definition
Molecular Weight: The mass of a molecule of a substance, calculated based on the atomic weights of its constituent atoms. Thermal Stability: The ability of a substance to retain its properties under high temperatures.
