What would you observe when (a) a saturated solution of potassium chloride prepared at 60^(@) C is allowed to cool at room temperature? (b) an aqueous sugar solution is heated to dryness? (c) a mixture of iron filings and sulphur powder is heated strongly?

Explain why non ideal solutions deviate from Raoult's law.

12 g of a saturated solution of potassium chloride at 20^@C , when evaporated to dryness, leaves a solid residue of 3 g. Calculate the solubility of potassium chloride.

Explain why : A solution is always clear and transparent.

Explain the meaning of the term 'saturated solution'. State two methods to convert a saturated solution to an unsaturated solution.

When a crystal of a solute are introduced into a saturated solution, the excess of solute crystallizes out and solution remains saturated (True/False).
