What is Potassium Bicarbonate?
Potassium Bicarbonate, also known as potassium hydrogen carbonate, is a white crystalline powder or granule. It is an inorganic salt with the chemical formula KHCO₃ and is identified by CAS number 298-14-6.
It is widely used as a buffering agent, leavening agent, pH regulator, potassium source and processing aid. In food applications, Potassium Bicarbonate is known as food additive E501(ii).
Because of its mild alkalinity and good solubility in water, Potassium Bicarbonate is used across food, agriculture, pharmaceutical, water-treatment and technical applications.
Applications Across Industries
Agriculture
Used in selected crop-care applications, foliar treatments and as a potassium source in agricultural formulations.
Pharmaceuticals
Used as an excipient, buffering agent and potassium source in selected pharmaceutical and healthcare formulations.
Water Treatment
Used for pH adjustment, alkalinity control and buffering in selected water-treatment applications.
Fire Extinguishing Powders
Used as an active ingredient in certain dry chemical fire-extinguishing powders.
Industrial Applications
Used in chemical processing, gas treatment, cleaning formulations and specialty industrial applications.

Frequently Asked Questions (FAQ)
What is Potassium Bicarbonate used for?
Potassium Bicarbonate is used in food processing, bakery products, agriculture, pharmaceuticals, water treatment, fire-extinguishing powders and industrial formulations.
Is Potassium Bicarbonate food grade?
Food-grade Potassium Bicarbonate is available and is used as food additive E501(ii). Suitability depends on the required specification and supporting documentation.
Is Potassium Bicarbonate the same as Sodium Bicarbonate?
No. Both are bicarbonate salts, but Potassium Bicarbonate contains potassium instead of sodium. It is often used where sodium reduction or potassium enrichment is desired.
Is Potassium Bicarbonate soluble in water?
Yes. Potassium Bicarbonate is soluble in water and forms a mildly alkaline solution.
Is Potassium Bicarbonate hazardous?
Potassium Bicarbonate is generally considered a low-hazard chemical, but dust may cause irritation. It should still be handled according to the applicable Safety Data Sheet.
Is Potassium Bicarbonate available in different grades?
Yes. Food, technical, industrial and pharmaceutical grades may be available depending on the required specification, quantity and destination.
