You tell tell if a solution is supersaturated if it cannot dissolve any more solute at any given temperature. You can not “mix” the solution anymore to dissolve the solute. If it is saturated, you would be able to dissolve the solute.
Answer:
The law of constant composition says that the composition of a homogeneous mixture is always the same
Explanation:
The law of constant composition that is also known as Proust's Law says that when two substances react with each other, to form a compound they will always do in a constant weight ratio, that is, the ratio of the masses between two substances that form a compound, must be proportional.
