Abstract
Burets, volumetric pipets, and volumetric flasks are essential for titration. Burets stands and pipet stands are also needed. It is guite much troublesome to prepare for this experiment. It takes much time and labor for students to get used to these kinds of glassware. However, it is possible to carry out a titration without any volumetric measurement at all, involving only mass measurement. Since titration is based on volumetric measurement, the author has planed a titration based on the mass measurement with an electronic balance. A new unit called weight molarity is introduced. Weight molarity is the concentration of a solution expressed in moles of solute per kilogram of solution. This unit makes a neat equation for a titration, and the method above streamlines the titration procedure very much; each student can therefore perform the experiment with ease and speed. It is high time for us to reconsider the conventional volumetric titration and replace it with a gravimetric one, now that electronic balances have become quite popular.
