Facts
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.
  
  • Copper rarely found in its pure form in nature.
  • Copper Sulfate is mostly used in agricultural poison and as an algicide in water purification system.
