KHCO

KHCO is an ambiguous term that may refer to different things depending on context, and it is not a standard chemical name or widely recognized entity. In chemistry, the closest established compound is potassium bicarbonate, whose correct formula is KHCO3. When KHCO appears without the trailing 3, it is often a typographical shorthand or a partial representation of KHCO3 rather than a separate substance.

Potassium bicarbonate (KHCO3) is a white, odorless crystalline salt that is highly soluble in water. It functions as a buffering agent and is used as a leavening agent in food production, particularly as a low-sodium substitute for baking soda in certain formulations. It is also used in agriculture as a contact fungicide and as a source of potassium for plant nutrition. In fire safety, potassium bicarbonate-based dry chemical powders are employed to suppress Class A and B fires by disrupting chemical reactions in flames.

Production and availability: KHCO3 is usually produced by reacting potassium carbonate with carbon dioxide or by processing potassium bicarbonate from natural brines and mineral sources. It is widely available as a pharmaceutical and food-grade additive, and in industrial grades for fire suppression and agricultural use.

Safety and regulation: Potassium bicarbonate is generally recognized as safe for use in food under appropriate conditions, but it can cause irritation to eyes, skin, or the respiratory tract if handling precautions are not followed. High doses can affect electrolyte balance. It should be stored away from acids and moisture; avoid inhalation of dust. See also related bicarbonates such as sodium bicarbonate and potassium carbonate.
