Question

What reaction vessel is typically used in an acid-base titration?

Answer 1

Is this not simply an `"Erlenmeyer flask........"`

Explanation:

Usually we would aim to have a FINAL volume LESS than `100*mL` in such a flask. Because when we do the titrations, i.e. adding approx. `20-30*mL` of titrant to `20-30*mL` of titrand, we want to agitate and shake the flask so that reaction is almost instantaneous. The curved sides of the flask allows the walls to be easily sluiced down with distilled water so that all the titrant gets into contact with the solution.

The straight bottom of the flask allows us to rest it on the bench, and often we rest it on a sheet of white paper so that we vizualize the colour change of the indicator.
