Magnesium Carbonate Light Extra Pure
Magnesium Carbonate (Light) Extra Pure is a fine, white, odorless powder known for its excellent absorbent, drying, and antacid properties. It is widely used in pharmaceutical formulations, cosmetics, food additives, and laboratory reagents. Its “light” form refers to its low bulk density, making it ideal for applications requiring a fluffy, easily dispersible powder. In personal care products, it serves as a filler and opacifier, while in pharmaceuticals, it acts as a mild antacid and magnesium supplement. Its high purity ensures consistent performance in analytical procedures and specialty chemical processes.
Magnesium Carbonate Light Extra Pure
Primary Laboratory Uses:
- Acid-Base Reactions:
- Frequently used in neutralization experiments to demonstrate reactions between carbonates and acids, producing CO₂.
- Drying Agent:
- Acts as a desiccant or moisture absorbent in laboratories due to its hygroscopic nature, especially in desiccators or drying tubes.
- Reagent in Inorganic Chemistry:
- Used as a source of magnesium ions (Mg²⁺) in analytical and synthesis reactions.
Secondary Laboratory Uses:
- Buffer Component:
- Sometimes used in buffer solutions or to maintain alkaline pH in chemical formulations.
- Preparation of Other Magnesium Compounds:
- Employed in reactions to synthesize other magnesium salts such as magnesium chloride or magnesium sulfate.
- Demonstrations and Teaching:
- Utilized in educational settings for simple reactions involving carbonates, decomposition, or thermal behavior.
