Not to be confused with Sodium bicarbonate. Potassium bicarbonate (also known as potassium hydrogen carbonate or potassium acid carbonate) is a colorless, odorless, slightly basic, salty substance.According to the U.S. Food and Drug Administration (FDA), potassium bicarbonate is  generally recognized as safe .There is no evidence of human carcinogenicity, no adverse effects of overexposure, and an undetermined LD50. It is among the food additives encoded by European Union, identified by the initials E 501.ccording to the U.S. Food and Drug Administration (FDA), potassium bicarbonate is  generally recognized as safe .

Potassium chlorate is a compound containing potassium, chlorine and oxygen atoms, with the molecular formula KClO 3.In its pure form, it is a white crystalline substance. It is the most common chlorate in industrial use.It is used.otassium chlorate readily decomposes if heated while in contact with a catalyst, typically manganese(IV) dioxide (MnO 2). Thus, it may be simply placed in a test tube and heated over a burner. If the test tube is equipped with a one-holed stopper and hose, warm oxygen can be drawn off.
