___________________
A solution in which no more solid material will
dissolve; additional material settles to the
bottom.
No more material will dissolve in the solution.

_________________
How much of the material dissolves in the
water.
Solubility is the property that substances
have of dissolving in solvents, such as the
solubility of salt in water.
