In the volumetric flask, drain the precious liquid. Prepare the volumetric flask containing the incoming solution. -To avoid contamination, wash the volumetric flask.
A volumetric flask defines a variety of laboratory flask that has been calibrated to hold a specific volume at a particular temperature. For precise dilutions including the creation of standard solutions, volumetric flasks are usually employed.
After the last dilution, the perfect solution is fully mixed by gently shaking the flask while it stays upside down. When it is gently tossed without inverting, the stirring is insufficient. The stopper keeps the neck from breaking right away if the flask tips over.
