MATTER - PROPERTIES AND TRANSFORMATION: Chemistry of Elements - Sulphur
The acid character of sulphur dioxide is demonstrated by its reaction with:
Calcium oxide.
Water.
Magnesium.
Calcium oxide and water.
What is the purpose of adding dilute nitric acid after adding barium chloride solution during the test for sulphate ions?
To prevent the formation of any precipitate.
To speed up the reaction.
To ensure complete precipitation of barium sulphate.
To dissolve any other white precipitates formed (e.g., barium carbonate or sulphite).
