Facts

Interesting Facts
  • Bismuth metal is soluble and reacts with concentrated nitric acid.
  • It oxides are used as a yellow pigment in paint. Bismuth chloride oxide BiClO gives a pearly texture to cosmetics.
  
  • 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.

Uses

Uses & Benefits
  • Tin and bismuth alloys have a very low melting point and hence it is used in fire detector and the fire extinguishers. It also used in electric solders and fuses.
  
  • 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.
