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.
  
  • Platinum is the rarest metal from the Precious metal categories..
  • Commercially Platinum is produced as a byproduct in ores of nickel.

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.
  
  • Platinum metal is mainly used in jewellery.
  • Platinum is used as an industrial catalyst in production of nitric acid, silicone and benzene.
