The apparatus required for the preparation of sulphur dioxide in the laboratory is shown here. Copper turnings are taken into the flask. Conc. sulphuric acid is poured into the thistle funnel until it covers the copper turnings. The flask is gently heated. Reaction takes place and sulphur dioxide is liberated in a continuous stream. Sulphur dioxide being heavier than air is collected in a gas jar by upward displacement of air.
