The main physical properties of sulphur are:

1. Sulphur usually occurs as a pale yellow, brittle, crystalline solid.

2. It has a faint characteristic smell, but no taste.

3. Sulphur is insoluble in water; it is not ever wetted by it. If a pinch of powdered sulphur is dropped into water, the particles will not sink but spread on the surface to form a yellow film.


4. Sulphur is highly soluble in carbon disulphide and sparingly soluble alcohol and ether.

5. It has a low melting point (114`C).

6. It occurs in a number of allotropic forms a two of which, the rhombic an d monoclinic, are crystalline.
