properties of sulphur dioxide

Properties of Sulphur Dioxide - Sulphur dioxide 'SO 2 ' a colorless gas with a pungent and suffocating odor. It is readily soluble in cold water, sparingly soluble in hot water, and soluble in alcohol, acetic acid, and sulfuric acid. It can be produ..

Sulphur dioxide gas exhibits bleaching properties in presence of moisture. It dissolves in water liberating nascent hydrogen. Coloring matter is bleached by reaction with nascent hydrogen. Nascent hydrogen removes oxygen atoms from the coloring matter (reduces coloring..

Vapor density : Its vapor density is 32, while the vapor density of air is 14.4. Hence sulphur dioxide gas is 2.2 times denser than ai..

Combustibility Sulphur dioxide gas is not combustible and ordinarily does not support combustion. The only exceptions are burning potassium or burning magnesium, which continue to burn in sulphur dioxide..

Uses of Sulphur Dioxide - It is a powerful germicide and insecticide and hence it is used a household fumigant. It can bleach delicate fibres. It undergoes easy liquefaction and vaporization and hence it is used as refrigerent in cold storage plants. It is used in the manufactur..

Sulphur dioxide is a dangerous air pollutant because of its corrosive properties; it irritates the eyes, nose, and lungs. It is produced by combustion of coal, fuel oil, and gasoline, since these fuels contain sulphur. The sulphur content of a fuel ..

Sulphur dioxide(SO 2 ) is one of the dangerous pollutant with a potentiality to form sulphuric acid, when mixed with water vapour. Water vapour commonly available in air can mix with SO 2 gas and produce sulphuric acid. Dry and Wet Acid Deposition or ..
