2 Facts
2.1 Interesting Facts
  • Barium oxidizes very easily in the air.
  • All toxic compounds of Barium can easily dissolve in water.
  • Barium carbonate is used to produce a Rat poison and its other compound Barium nitrate is used in fireworks to produce green color.
  • Chromium is highly reactive, hence it is not found free in nature.
  • Ores of Chromites mineral are the major source of Chromium metal.
  • Almost 90% leather tanning is done with the help of chromium.

4 Uses
4.1 Uses & Benefits
  • It is sued in chemical paint manufacturing and glass manufacturing.
  • Compounds of this metal are toxic; but still the barium sulfate is insoluble and given to patients suffering from digestive disorder.
  • It is used to harden the steel and produces a stainless steel and other various alloys.
  • It is also used to give proper finish to polished mirrors. Its chromium plates are used in bathroom fittings.
