Separation technique(1)

There are many separation techniques and the one I will be explaining in this post will be evaporation.

Evaporation

Evaporation is a separation technique used when we want the solute and not the solvent, which will we evaporated. We use this technique and not filtration because sometimes, things like salt can dissolve in the water into tiny particles that cannot be filtrated. However, the disadvantage would be that we cannot get the solvent because it is already being dissolved away.
