Nature

Sulphur at room temperature is a yellow, hard, crystalline, brittle solid. It is almost odorless and tasteless.

Melting point

When heated rapidly sulphur melts at 112.8^oC, and if heated slowly, it melts at 118.6^oC.

Boiling point

Sulphur boils at 444.6^oC and gives off light yellowish orange vapor.

Solubility

It is insoluble in water, sparingly soluble in alcohol and ether, and readily soluble in carbon disulphide, carbon tetrachloride, xylene, acetone, etc.

Conductivity

Sulphur is a non-conductor of heat and electricity. However, a lump of sulphur when rubbed by dry hand, or with wool, becomes electrostatically charged.

Effect of heat

When heated, sulphur undergoes a series of changes as discussed in section 13.5 above.
