04. Which two methods can be used to separate a salt from its solution in water? 1 crystallisation
2 decanting
3 distillation
4 filtration
А 1 and 2
B 1 and 3
C 2 and 3
D 3 and 4

i think option b

C 1 and 3

Explanation:

Simple distillation is a method for separating the solvent from a solution. For example, water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt. When the solution is heated, the water evaporates.

Crystals grow because salt molecules in the solution meet up and interlock. As they do so, they fit together like puzzle pieces, arranging themselves in a lattice structure, thus creating a crystal nucleus. ... it crystallizes.

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).
