Final answer:
Saturation means to fully absorb something, such as water soaking a sponge. When a solute's concentration is equal to its solubility, the solution is saturated with that solute. If the solute's concentration is less than its solubility, the solution is said to be unsaturated. A solution that contains a relatively low concentration of solute is called dilute, and one with a relatively high concentration is called concentrated.
Step-by-step explanation:
Saturation means to fully absorb something, such as water soaking a sponge. When a solute's concentration is equal to its solubility, we say that the solution is saturated with that solute. If the solute's concentration is less than its solubility, the solution is said to be unsaturated.
A solution that contains a relatively low concentration of solute is called dilute, and one with a relatively high concentration is called concentrated.
