Magnesium Carbonate is a white, odorless solid that occurs in crystalline or powder form, widely utilized across industries for its unique chemical properties. With a CAS number of 546-93-0 and a molar mass of 84.31 g/mol, this compound is slightly soluble in water, forming a basic solution, while exhibiting greater solubility in acidic solutions due to its reactivity with acids. The product is alkaline when suspended in water, making it essential for applications requiring pH moderation. It decomposes upon heating between 350–400°C, releasing carbon dioxide and magnesium oxide, thus finding relevance in thermal processes. The anhydrous form of magnesium carbonate has a density of 2.958 g/cm³, with hydrated forms having variable densities depending on the extent of hydration. This chemical is prevalently used in pharmaceuticals, cosmetics, food additive formulations, and industrial manufacturing sectors due to its diverse functional characteristics.
