Properties of Hydrogen Sulphide

Topic Content:

Physical Properties of Hydrogen Sulphide:

1. Hydrogen sulphide is a colourless gas with a very offensive smell like that of a rotten egg. 

2. It is sparingly soluble in water at ordinary temperatures but insoluble in boiling water. 

3. It is a poison gas

4. It is slightly denser than air.

5. It has a densityDensity is the measurement of how tightly a material is packed together i.e. how closely the particles are packed in the material. The tighter the material is packed the more its... More of 1.18 g/cm³ .

6. It burns with a pale blue flame.

Chemical Properties of Hydrogen Sulphide:

Acidic Properties:

Hydrogen sulphide ionizes slightly in water to form a weak dibasic acid.
