Question

What are the property of salt?

Answer 1

Salt is a chemical compound with a number of interesting properties:
Crystals or white crystalline powder.
Transparent and colourless in crystalline form – rather like ice.
Crystallises in the isometric system, usually in the form of cubes.
Soluble in water (35.6g/100g at 0°C and 39.2g/100g at 100°).
Slightly soluble in alcohol, but insoluble in concentrated hydrochloric acid.
Melts at 801°C and begins to vaporize at temperatures just slightly above this boiling point 1,413°C.
Hardness of 2.5 on the MOH scale of hardness.
Specific gravity of 2.165.
Non-combustible – low toxicity.
Hygroscopic – absorbs moisture from damp atmospheres above 75 per cent relative humidity – below this, it will dry out.
