• Manganese Salt

    Manganese Salt

    A permanganate is the general name for a chemical compound containing the manganite ion, (MnO−4). Because manganese is in the +7 oxidation state, the permanganate ion is a strong oxidizing agent. The ion has tetrahedral geometry. Permanganate solutions are purple in color and are stable in neutral or slightly alkaline media.

  • Chromium


    Chromate salts contain the chromate anion, CrO2−4. Dichromate salts contain the dichromate anion, Cr2O2−7. They are oxyanions of chromium in the 6+ oxidation state. They are moderately strong oxidizing agents. In an aqueous solution, chromate and dichromate ions can be interconvertible.

  • Fluorosilicate


    White odorless and tasteless hexagonal or cubic crystal or powder. The relative density is 3.08 (hexagonal) or 2.665 (cubic, 17 ° C). It is hygroscopic. Slightly soluble in water, soluble in hydrochloric acid, solubility slightly increased with increasing temperature. Insoluble in alcohol. Hydrolysis in hot water produces silicic acid.
