Potassium carbonate is a chemical compound from the salt family that has a high alkaline property and is used as a base material in various industries. This compound is produced from the reaction between carbon dioxide and potassium hydroxide. In this process, potassium carbonate and water are formed as the final products. After the reaction, the water present is separated through filtration and evaporation processes, and pure potassium carbonate is obtained. This chemical is available as a white, water-soluble powder and is used in the production of glass, detergents, the food industry, and also in adjusting the pH in industrial processes. In addition, potassium carbonate is also used in softening hard water and removing mineral deposits due to its alkaline property.

Environmental impact of Potassium carbonate
Potassium carbonate generally has little environmental impact, but if released excessively into the environment, it can cause pH changes in water and soil, which are harmful to living organisms. It dissolves easily in water and can disrupt the chemical balance of water resources. Therefore, waste containing potassium carbonate should be disposed of in a way that prevents contamination of water and soil resources.
Safety Measures and Regulations for Handling Potassium carbonate
Personal protective equipment such as gloves, safety glasses and a mask should be worn when working with potassium carbonate, as direct contact with the skin or eyes can cause irritation or burns. The chemical should be stored in tight containers in a cool, dry environment to prevent moisture absorption and unwanted reactions. In the event of a spill or leak, the area should be cleaned up promptly and the waste disposed of in accordance with environmental regulations. Also, when used in enclosed spaces, adequate ventilation is required.
