Chemical properties of Non-metals
Reaction of non-metals with oxygen:- Non-metals form respective oxide when react with oxygen.
(1) When carbon reacts with oxygen, carbon dioxide is formed along with production of heat.
(2) When carbon is burnt in insufficient supply of air, it forms carbon monoxide. Carbon monoxide is a toxic substance. Inhaling of carbon monoxide may prove fatal.
(3) Sulphur gives sulphur dioxide when react with oxygen. Sulphur caught fire when exposed to air.
(3) When hydrogen reacts with oxygen it gives water.
Non-metal oxides are acidic in nature. Solution of non-metal oxides turns blue litmus red.
Carbon dioxide gives carbonic acid when dissolved in water.
Sulphur dioxide gives sulphurous acid when dissolved in water.
Sulphur dioxide gives sulphur trioxide when reacts with oxygen.
Sulphur trioxide gives sulphuric acid when dissolved in water.
Reaction of non-metal with chlorine:
Non metals give respective chloride when react with chlorine gas.'
Hydrogen gives hydrogen chloride and phosphorous gives phosphorous trichloride when react with chlorine.
