Potassium chromate (K2CrO4) is used in inks, dyes, and stains (bright yellowish-red colour), in explosives and fireworks, in safety matches, in the tanning of leather and in fly paper. Potassium fluorosilicate (K2SiF6) is used in specialized glasses, ceramics, and enamels. Potassium sodium ...
Potassium is non-water soluble, but it does react with water as was explained earlier. Potassium compounds may be water soluble. Examples are potassium dichromate with a water solubility of 115 g/L, potassium permanganate with a water solubility of 76 g/L, potassium iodide with a water solubil...
hydroxide (also called causticpotash), which readily absorbs moisture and is employed in making liquid soaps and detergents and in preparing many potassiumsalts. Reaction ofiodineand potassium hydroxide producespotassium iodide, KI, which is added to table salt and animalfeedto protect againstiodine ...
UsesPotassium bromide was used as a secondary halide in combination with an iodide in the paper negative processes, the albumen on glass process, and the wet collodion processes. When silver bromide gelatin emulsion was invented, potassium bromide was the primary halide. It was also used in combi...
