Question

State one advantage and one disadvantage of evaporation to dryness over crystallization of the solution

Answer 1

Answer:

It is a method used to obtain a solute from a solution. For example, solid salt (solute) may be recovered from a salt solution by evaporating all the water (solvent) away. One disadvantage of evaporation to dryness is that any soluble impurity present will be deposited together with the required solid

Answer 2

✷three advantages are

in evaporation the soluble impurities (and insoluble impurities sometimes) are mixed but crystallization process separates the soluble and insoluble impurities from the solid

in evaporation the resultant object obtained is in powdery form but in crystallization it is pure crystal

In evaporation, the solution is heated to dryness, so some solids like sugar may get charred but it is not so in process of crystallization hope this helps

Disadvantages of crystallization:

1. Some substance remains with the liquid/solvent.
2. Liquid needs to be purified for further use
