In laboratories, it is common practice to prepare a solution from a concentrated mother solution.
Example: one wants to prepare a volume V = 100 mL of a daughter solution of concentration C = 0.010 mol.L-1 from a mother solution with a concentration C = 0.10 mol.L-1.
The preparation technique for such a solution is to prepare a dilution. This simple procedure is carried out using a very precise experimental protocol.
