A procedural change would be required so that the student includes an indicator, like phenolphthalein, in the tomato juice sample, which changes color at the endpoint of the titration. This indicator helps visually identify when all the acid in the tomato juice has been neutralized by the NaOH solution, ensuring accurate determination of the juice's acidity.
