An analytical chemist is determining the total acidity of a batch of white wine (primarily tartaric acid) by titrating a sample against a standardised solution of sodium hydroxide. The chemist decides against using universal indicator to identify the equivalence point of this titration.
Explain why universal indicator is unsuitable for determining the precise endpoint of this titration.
