Question

What does solubility mean?

Answer 1

So basically there are two things you need to know

Solute = what you put into a solvent
Solvent the substance, liquid you put your solvent in.

Solubility means how much of a solute that can dissolve in a solvent.

Now say you have water and you put salt into it.

Water is your solvent and salt is your solute.

Remember like dissolves like so polar solute a will dissolve in polar solvents.

Answer 2

Remember solvents can only accept a certain amount of solute. Once the maximum amount of solute is dissolved we call that saturated solution. If you keep putting say salt in water there will be a point where it will precipitate, you'll see salt collecting at the bottom.
