Potassium hydrogen carbonate(CAS: 298-14-6)

Potassium hydrogen carbonate, with the chemical formula KHCO3, is a white, crystalline, water-soluble compound. It functions as a weak base and is commonly used in buffering solutions. Also known as potassium bicarbonate, it has a pH of around 8.3 when dissolved in water, making it useful in applications requiring mild alkalinity.

Potassium hydrogen carbonate is widely used in pharmaceuticals as a buffering agent, in the food industry as a leavening agent or acidulant, and in industrial processes for chemical synthesis. It also serves as a source of potassium in research and is employed in fire extinguishing systems due to its ability to release carbon dioxide.

Potassium hydrogen carbonate is generally considered safe when handled properly. It has low toxicity but may cause irritation if inhaled or ingested in large amounts. Safety precautions include wearing protective gloves and goggles, avoiding skin contact, and ensuring adequate ventilation. It complies with standard safety regulations for chemical handling.

Potassium hydrogen carbonate should be stored in a cool, dry, and well-ventilated area, away from moisture and direct light. It requires a sealed container to maintain stability and prevent clumping. Storage conditions should ensure temperatures below 25°C and humidity levels below 60% to preserve its chemical integrity.
