Good Laboratory Practice: When using a volumetric flask, a solution should be diluted stepwise. The solution to be diluted is added to the flask, and the diluent (usually distilled water) is added to fill the flask about two-thirds (ensuring that any reagent on the ground glass lip is rinsed down).
