Facts
Interesting Facts
  • Osmium metal does not oxidize in air unless it is heated.
  • But if it heated den it forms Osmium Tetroxide, which is highly toxic.
  
  • 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.
