# Dilution Factor Calculations

## Key Concepts

- Dilution means to reduce the concentration of a solution.
- A solution is produced when a solute dissolves in a solvent.
- Concentration refers to the amount of solute dissolved in a volume of solution.
- A solution can be diluted by adding more solvent to the solution, then
(i) volume of solution increases from V

_{intial}to V_{final}

(ii) concentration of solution decreases from c_{initial}to c_{final} - Dilution factor refers to the ratio of the volume of the initial (concentrated) solution to the volume of the final (dilute) solution
^{1},that is, the ratio of V

_{1}to V_{2}

or

V_{1}: V_{2} - A dilution factor, DF, can be calculated:
DF = V

_{2}÷ V_{1}
