MATTER - PROPERTIES AND TRANSFORMATION: Chemistry of Elements - Sulphur
What is the main reason why sulphur is used in the vulcanization of rubber?
To make it colourful.
To make it less elastic.
To make it more soluble in water.
To improve its strength and elasticity.
Concentrated sulphuric acid is often used as a dehydrating agent. This property is demonstrated by its action on:
Sodium hydroxide.
Carbon.
Zinc metal.
Sugar.
Sulphur is found in nature in which of the following forms?
Only as sulphides and sulphates.
Both as free element and in combined states (sulphides, sulphates).
Only as sulphur dioxide.
Only as free element.
Sulphur dioxide can be prepared in the laboratory by the reaction of dilute hydrochloric acid with:
Sodium sulphate.
Sodium thiosulphate.
Sodium sulphide.
Sodium sulphite.
Which of the following metals does NOT react with dilute sulphuric acid to produce hydrogen gas?
Iron.
Magnesium.
