Why it is preferable to allow the hot solution to cool gradually instead of chiling immediately in an ice -bath?
If you cool too quickly, a saturated solution at a higher temperature can 'crash' out of solution.

Why calcium is obtained by electrolysis of molten calcium chloride rather than its solution?
if done in water solution, the extracted calcium would immediately react with the water to form calcium hydroxide.

Why the amount of saturated solution decreses when forming crystals?
Crystals form when the solution has been pushed past its saturation point; this can most easily be done by "seeding" the solution or by chilling it (because temperature decreases solubility). As the crystal forms, the solute (dissolved substance) is drawn out of solution, lowering the concentration of the overall solution.
Why iodine solution stored in coloured bottled?
Iodine solution reacts with light to undergo a photodecomposition reaction and therefore must be stored in amber bottles to minimise the amount of light that the solution is exposed to. If stored in a clear bottle it will gradually break down as the iodide ions are gradually converted to iodine and the solution turns a yellowish colour.
