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 permanganate is an inorganic chemical compound with the chemical formula KMnO 4. It is a salt consisting of K+ and MnOâ 4 ions. Formerly known as permanganate of potash or Condy's crystals, it is a strong oxidizing agent.It dissolves in water to give intensely pink or purple solutions, the evaporation of which leaves prismatic purplish-black glistening crystals.In 2000, worldwide production was estimated at 30,000 tonnes.cidic solutions of permanganate are reduced to the faintly pink manganese(II) ion (Mn 2+) and water. In neutral solution, permanganate is only reduced by three electrons to give MnO 2, wherein Mn is in a +4 oxidation state.
