name the four process involved in the separation of mixture of salt and sand​

Answer 1

Decantation - Oil floats on water (oil is insoluble in water), so it can be decanted easily.

Filtration- Filter the mixture and sand will be separated from the water (as it is insoluble in water), and only salt solution will be left.

Evaporation

Mixtures can be separated using a variety of techniques.

• Mixtures can be separated using a variety of techniques.Chromatography involves solvent separation on a solid medium.
• Mixtures can be separated using a variety of techniques.Chromatography involves solvent separation on a solid medium.Distillation takes advantage of differences in boiling points.
