Request SDS →Potassium bicarbonate (CAS 298-14-6) is the potassium salt of carbonic acid, KHCO3. Established uses include leavening in baking, acidity regulation and buffering as a food additive, and service as a dry-chemical fire-extinguishing agent. It also functions as a carbon-dioxide-releasing and pH-adjusting agent in processing and formulation.
Frequently Asked Questions
What is potassium bicarbonate used for?
Potassium bicarbonate (KHCO3, CAS 298-14-6) is used as a leavening (carbon-dioxide source) in baking, as a food-additive acidity regulator and buffer, as the active agent in dry-chemical fire extinguishers, and as a mild alkali for process and formulation pH control.
What is the chemical formula for potassium bicarbonate?
Potassium bicarbonate is KHCO3 (formula CHKO3), the potassium salt of carbonic acid, CAS 298-14-6. It is supplied here as a USP crystalline powder grade.
Is potassium bicarbonate the same as baking soda?
No. Baking soda is sodium bicarbonate (NaHCO3); potassium bicarbonate is the potassium analog (KHCO3). Both release carbon dioxide and act as leavening and pH agents, but they are distinct salts with different cations and specifications.
What does USP crystalline powder grade mean here?
USP refers to United States Pharmacopeia compendial specifications, and crystalline powder describes the physical form. We supply against the product CoA and SDS; request both to confirm the grade and lot specifications meet your application.
How is bulk potassium bicarbonate packaged and quoted?
It is typically supplied in bags, drums, or supersacks. Submit a bulk RFQ with your quantity and packaging for current pricing with CoA and SDS; HS classification is 2836.40.
