Concentration

1. Saturated solution: At any particular temperature, are solution that has dissolved as much as it is capable of dissolving, it is said to be a saturated solution
2. Unsaturated solution: If the amount of solute contained in a solution is less than the saturation label, it is called an unsaturated solution.
3. Solubility: The amount of solute present in the saturated solution at this temperature is called its solubility.

• The concentration of solution is the amount of solute present in a given amount (mass or volume) of solution, or the amount of solute dissolved in a given mass or volume of solvent.

$$\text{Concentration of solution} = \frac{\text{Amount of solute}}{\text{Amount of solution}}$$

Two methods to find the mass or volume percentage of a solution.

• $$\text{Mass by mass percentage of solution } = \frac{\text{mass of solute}}{\text{mass of solution}} * 100$$
• $$\text{Mass by volume percentage of solution} = \frac{\text{mass of solute}}{\text{mass of solution}} * 100$$
