Why do you not need to be exact when making your stock NaOH solution in Part A of the experiment?
Simply so, why is there a need to standardize the NaOH solution? First of all, solid NaOH absorbs water from the air, so accurately weighing a sample during the preparation of a solution is impossible. Once the NaOH solution has been standardized and its concentration is well-known, it can be used to titrate other acid…
