Pouring off can only separate solids or liquids with a different density than the solution.
Gently force the liquid through a permeable membrane (such as filter paper)whose pores are smaller than the particle size of the insoluble solid you wish to remove from the solution.
Distillation
We can get a pure solid from a liquid by freezing the solution.
Heating the solution water is deleted by evaporation.
No. Liquids cannot be separated by filtering. A method to separate mixed liquids is distillation.
Evaporation + crystallization
By evaporation the liquid is deleted.
settling
screening
precipitation
The simplest method is the distillation of the solution.
The process is distillation.
