Volumetric liquid dosing: Difference between revisions

Line 47:

After weighing the material, calculating the concentration, and measuring the required volume of solvent, add the liquid to a suitable container, then carefully mix in the compound. Seal tightly, then mix thoroughly by shaking the container vigorously.

To aid in dissolution, the container can be placed in a heat bath to warm it up. After a while, the solvent will become less viscous and can be mixed more thoroughly. Be vigilant of the amount of heat used in the hot water bath - boiling water may break down some chemical compounds.

Some chemicals need the aid of an acid to dissolve in water ~~- weak~~ acids such as white vinegar or even citric acid are both valid options, but food grade acetic acid (vinegar) would be the most sterile way of adding an acid into the solution.

*Label the container with contents and concentration

*Keep in a safe place away from children

*Periodically check the solution for homogeneity - there should be no particulate matter precipitating out on the bottom of the bottle. The solution should be evenly mixed and homogeneous.
