Chemical element of metals. Cu comes from Cuprum, Fe comes from Ferrum, Ag from Argentum. The symbols were not followed by a period (full stop) as with abbreviations. Later chemical elements were also assigned unique chemical symbols, based on the name of the element, but not necessarily in English. For example, sodium has the chemical symbol 'Na' after the Latin "natrium". The same applies to "W" (wolfram) for tungsten, "Fe" (ferrum) for iron, "Hg" (hydrargyrum) for mercury, "Sn" (stannum) for tin, "K" (kalium) for potassium, "Au" (aurum) for gold, "Ag" (argentum) for silver, "Pb" (plumbum) for lead, "Cu" (cuprum) for copper, and
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
