Potassium tree leaves, adding water, heating, and evaporating the solution. When Humphry Davy first isolated the pure element using electrolysis in 1807, he named it "potassium", which he derived from the word potash. The symbol "K" stems from "kali", itself from the root word "alkali", which in turn comes from "" "al-qalyah" "plant ashes." In 1797, the German chemist Martin Klaproth discovered "potash" in the minerals leucite and lepidolite, and realized that "potash" was not a product of plant growth but actually contained a new element, which he proposed to call "kali". In 1807, Humphry Davy produced the element via electrolysis:
Potassium bromate use in 2005, claiming they had new production methods to reduce the amount of the chemical which remained in the final product. Potassium bromate Potassium bromate (KBrO), is a bromate of potassium and takes the form of white crystals or powder. It is a strong oxidizing agent. Potassium bromate is produced when bromine is passed through a hot solution of potassium hydroxide. This first forms unstable potassium hypobromite, which quickly disproportionates into bromide and bromate: Electrolysis of potassium bromide solutions will also give bromate. Both processes are analogous to those used in the production of chlorates. Potassium bromate is readily
