Sulphur dioxide is a reducing agent, it reduces ferrio chloride to ferroua chloride. The sulphur dioxide in presence of water is oxidized: to sulphuric acid. 502+ 2FeCl + 2H20.
=
27eC12
H2SO + 2HC1
When sulphur dioxide is passed into caustic sode, the normal salt is formed initially: SO, + 2NaOH = Na, 50, +K20
However, further reaction of the normal salt with sulphur dioxide yields the acid salt:"
+ Na 50+ H2O = 2NaHS0

Only zinc, but not iron, dissolves in sodium hydroxide solution, forming the zincate: Zn + 2NaOH = Na Zno2 + H2

Both sulphur and silicon will react directly 'with chlorine,

When the sodium hydroxide solution is cold and dilute, chlorine will react to form a mixture of sodium chloride, and sodium hypochlorite Cl2+ 2NaOH = NaCl + Nac10+ H20
The gas is nitrous oxide (by dry heating of the solid) and also ammonia (by action of sodium hydroxide on an ammonium salt); NH NO3

Ferrous sulphate decomposes on heating to ferric oxide, liberating sulphur dioxide and sulphur trioxide:
