In the titration of iron (ll) solution with potassium dichromate,why should the beaker be dry but not necessarily the conical flasks
Accepted Answer
In the titration of iron(II) solution with potassium dichromate, the beaker containing the iron(II) solution should be dry because the presence of water can dilute the solution, affecting the accuracy of the titration. Water can react with potassium dichromate, leading to a change in the concentration of the titrant. However, the conical flasks used for the titration do not need to be dry, as the volume of the solution is measured in the flask, and the addition of water to the flask does not significantly affect the overall volume.
