Questions asked by users might not always be phrased in the clearest way.
Given an iron solution of unknown concentration in a beaker, why should the beaker be dry but the conical flask which will be used during titration can be wet
Accepted Answer
The beaker containing the iron solution of unknown concentration should be dry to ensure accurate measurement of the solution's volume. Water droplets on the beaker's surface can dilute the solution, leading to an inaccurate concentration determination. However, the conical flask used during titration can be wet because the volume of the solution being titrated is not critical. The titrant, which is added from a burette, is the solution whose volume is carefully measured. The water in the conical flask will not affect the titration results.
