![]() ![]() In order to prevent contamination of this stock solution, place a small amount of it in a clean, dry, conical flask (erlenmeyer flask), swirl it around and then discard this solution appropriately.ĭO NOT use water or any other solvent to rinse the flask because adding more solvent would dilute the solution and we would no longer know what the concentration of this solution is. This solution is referred to as the stock solution. The solution to be diluted will be in a vessel such as a volumetric flask. A way of adding the pure solvent to the volumetric flask, for example a glass funnel and a pasteur pipette.A container of pure solvent, the same solvent used to make the original solution, such as water.A pipette to remove a known volume of this solution from the container and transfer it to a new container such as a volumetric flask.This is the stock solution, the solution to be diluted. A container of solution of known concentration.No ads = no money for us = no free stuff for you! Dilution Techniqueĭilution means to reduce the concentration of a solution.Ī solution can be diluted by adding solvent to a given volume of stock solution. Determine concentration of dilute solutionĭetermine concentration of stock solution ![]()
