State and explain four physical properties of Sulphur.
1. - It is a yellow solid which exists in one amorphous form and 2 crystalline forms.
- A molecule of sulphur consists of a pluckered ring of 8 sulphur atoms covalently bonded.
2. Solubility
- It is insoluble in water but soluble in organic solvents like carbon disulphide, xylene and toluene.
3. It is a poor conductor of heat and electricity since it is a covalent element lacking free electrons or ions.
4. Effects of heat
- When sulphur is heated out of contact with air, it melts at low temperatures of about 113oC to form an amber (orange) coloured mobile liquid.
Reason:
- The S8 rings open up to form chains of S8.
