Carbonates are a class of inorganic compounds and ions characterized by the carbonate anion ($\text{CO}_3^{2-}$). These compounds are found extensively in nature, forming crucial geological structures such as limestone and marble, and serving as structural materials in numerous biological systems. Chemically, the balance of carbonate ions is vital in aqueous solutions, playing a key role in regulating pH balance within biological fluids. Industrially, carbonate materials are valuable commodities utilized in processes ranging from the manufacturing of construction materials like cement to the production of pigments and buffers. Their chemical versatility allows them to function both as structural solids and as essential components in various chemical reactions and purification technologies.
