When chlorine gas is passed into a solution of sulphur dioxide?
sulphur dioxide is reduced to sulphur
the chlorine is oxidized to hydrochloric acid
dilute sulphuric acid and hydrochloric acid are produced
Hydrochloric acid and sulphur are produced
sulphur trioxide is the only product
Correct answer is C
- When sulfur (IV) oxide or sulfur dioxide is passed on with chlorine gas, mixture of acids are formed.
- It leads to the formation of sulfuric acid and hydrochloric acid.
- This is a redox reaction

Which of the following statement is false?
Acids react with some metals, liberating hydrogen
Acids react with carbonates, liberating carbondioxide
Acids conduct electricity and are decomposed by the current, liberating hydrogen at the anode
Acids have a sour taste
Acids change the colour of indicators
Correct answer is C
Thus, with a dilute solution of sulphuric acid and platinum electrodes, hydrogen gas is evolved at the cathode
