What could be the effects of carbonate error on the calculated values for the standardization and the sample analysis?
What could be the requirements for a compund to be able to undergo double indicator titration?
IF the standardization AND sample analysis is done with the same indicator, the error cancels. There is a discussion of this in your text. It is in the same area as you read for prep of NaOH and standardization of NaOH.
