Boiling
What is this method of separating substances called?
Chromatography
This picture shows distillation - pure water is being separated from salty water. How do you think it works?
The pure water boils and evaporates and then condenses back into pure water, leaving the salt behind, as salty water boils at a higher temperature
The picture on the left is a salt solution. The picture on the right is a SATURATED salt solution. What is the difference?
The saturated solution cannot dissolve any more salt. (In fact there is excess salt as some hasn't dissolved)
A substance than cannot dissolve in a liquid is.......
Insoluble
