To the mobile versionDilutionIn a dilution the concentration of a solute in a solution is reduced by adding more solvent (often water) to the solution. In the laboratory, frequently the ratios of concentrations (c1/c2 or c2/c1) are given and the solvent is added to the volume V1 of the initial solution to yield the final volume V2. In household and trade often the volume of the initial solution V1 and the volume of the added solvent ΔV are prescribed.
Usage:
Always choose the correct unit in the corresponding pull-down-menu
before you type a value of a concentration or volume. Example: From a solution with a concentratiion of 0.1 mol/l you want to prepare 500 ml of a solution with a concentration of 2 mmol/l. After you have chosen the correct units, type the two concentrations into the corresponding fields. After a click the ratios are displayed, e.g. V1/V2 = 0.02. Now choose the unit "ml" and type the volume wanted for the final solution "500". After another click you can read the result: You need 10 ml of the initial solution, filled up with solvent to 500 ml to yield a 2 mmol/l solution.
