1 Answer

Answer :

crystallisation is a process that separates a pure solid in the form of its crystals from a solution. Crystallisation is better than evaporation because during Evaporation. Some solids decompose or some, like sugar, may get charred on heating to dryness. ... In such cases, the crystallisation technique is applied.

(2) stabilise the colloid and prevent crystallisation Explanation: Gelatine, being a colloid, has the property of preventing crystallization. In ice lollies and icecream this is demonstrated by the formation of a very fine crystal structure on freezing. This goes much further in that gelatine stabilized icecream does not become grainy or sandy due to the slow crystallisation of lactose with time.
