Question

Which of the following statement correctly justifies that crystallisation technique considered better than simple evaporation to purify solid? Solid decompose or get charred on heating to dryness. Impurities may remain dissolved in the solution even after filtration Both (a) and (b) Impurities are easily removed in solution.​

Answer 1

Answer:

b is a answer isa impurities are easily removed in solution

Answer 2

Answer:

Step by step answer: The crystallization technique is better than evaporation because the extent of purification with crystallization is very high as it does not require very high-temperature conditions. Hence, there is no need to boil the solvent.
