twhy caustic soda is in zinc cyanide process

  • redoxWhy does zinc react with sodium hydroxide

    In effect zinc is not displacing sodium. It's displacing hydrogen. We expect a metal to do this from a hydroxide base if. the metal is more reactive than hydrogen and; the metal's own hydroxide can act as acid towards this base amphoteric hydroxide. Zinc passes both tests and so, party time!

  • Sodium hydroxideWikipedia

    Sodium hydroxide, also known as lye and caustic soda, is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na+ and hydroxide anions OH. Sodium hydroxide is a highly caustic base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. It is highly soluble in water, and readily absorbs

  • Zinc Cyanide Plating ProcessMineral Processing & Metallurgy

    The amount of zinc oxide equivalent to the zinc cyanide is equal to 75 g/l x 0.7 = 52.5 g/l. The use of this amount of zinc oxide would liberate an equal amount of sodium hydroxide. In solution I, where 60 g/l of sodium hydroxide is desired, the full amount of sodium hydroxide will be required.
