Potassium Carbonate Extra Pure is a high-purity, white, hygroscopic, water-soluble salt with the chemical formula K₂CO₃. It is known for its alkaline properties and exceptional solubility in water, forming a strongly basic solution that is widely used in laboratory and industrial processes. Its Extra Pure grade ensures it meets stringent standards for research, analytical, and high-spec formulation work.

This compound is essential in buffer preparation, pH adjustment, and titration analysis in laboratory chemistry. It also serves as a drying agent for certain solvents and gases due to its moisture-absorbing nature. In industrial applications, Potassium Carbonate is a key ingredient in the manufacture of glass, soaps, and dyes, and is also used in fermentation processes to control acidity. In the food industry, it functions as a food additive (E501), commonly used as a buffering or raising agent in baking.

To maintain its quality, Potassium Carbonate Extra Pure should be stored in a tightly sealed container, in a dry and cool environment, away from acids and moisture, as it readily absorbs water and carbon dioxide from the air. Proper handling using protective gloves and eye protection is advised, especially in concentrated solutions, due to its caustic nature.
