How is a solution saturated?
What happens if we continue to add salt to a salt-water solution? If we keep
on adding salt to water and keep on stirring, after sometime, no more salt
would dissolve because the solution is saturated (filled up). The water gets
saturated with salt because all its inter-molecular spaces are occupied.

TYPE OF SOLUTIONS
Generally solutions are solids dissolved in liquids.
They could also be gases dissolved in liquids.
They can also be a combination of gases and
liquids. If you mix things up and they stay at an
even distribution, it is a solution.
You have learnt about many liquid-solid solutions. Let's look at some other
type of solutions :
Did You Know?
Water is one of the few known substances which expands when it freezes. Thus,
ice occupies more space than water.

Liquids that dissolve in water are called miscible liquids.
Liquids that do not dissolve in water are called immiscible liquids.
Miscible liquids dissolved in water make a liquid-liquid solution.

What happens when we boil water? When we boil water, bubbles form on the
sides of the vessel. These are bubbles of the gases that are dissolved in water.
So, water is an example of a liquid-gas solution. Carbon dioxide is added to
aerated drinks to give it a fizz.
