Key Properties
Potassium bicarbonate (extra pure, potassium hydrogen carbonate) is a mild alkaline salt widely used as an antacid and food-additive reference compound. It is recognized for its ability to neutralize acids and is commonly utilized in various applications, including food processing and pharmaceuticals. This compound is characterized by its high purity level of 99.5%, making it suitable for sensitive applications where contaminants must be minimized. Its mild alkalinity and solubility in water further enhance its versatility in both laboratory and industrial settings.
Also known as Potassium hydrogen carbonate.

- Substance
Potassium bicarbonate appears as a white crystalline powder with a fine texture. It is highly soluble in water, with a solubility of approximately 96 g/L at 20°C. The compound has a melting point of 100°C (decomposes) and a boiling point that is not applicable as it decomposes before boiling. The density of potassium bicarbonate is about 2.17 g/cm³. It has a neutral pH in solution, typically around 7, and does not have a strong odor, making it suitable for use in food applications.

Potassium bicarbonate is widely used as an antacid, providing relief from heartburn and indigestion by neutralizing excess stomach acid. In the food industry, it serves as a leavening agent in baking, helping dough to rise by producing carbon dioxide when it reacts with acids. Additionally, it is employed in analytical chemistry as a reference compound due to its stable properties. Other applications include its use in fire extinguishers, as a buffering agent in swimming pools, and in agriculture as a mild fungicide and nutrient source for plants.
