If you had prepared a solution of a standardized reagent, what would be the best to prepare a receiving flask?

Answer 1

The best measure would be to flush the receiving vessel with a small volume of the reagent.

A small volume of your reagent should be sacrificed. Pour in a few milliliters, rinse and shake the container, and then repeat the process. Finally, refill the container with your standardized reagent. You have a reagent of known concentration that you want to transfer into another vessel. Even if the other vessel is completely dry, there could be a residue that would react with the transferred reagent.
