What should be done if a dark pink color persists during the titration process?

Add more deionised water to dilute the solution

Stop the titration and record the final burette reading (correct)

Continue adding the titrant drop by drop

Add more indicator solution

Why is it important not to add too much indicator in volumetric analysis?

To make the titration process longer

To speed up the reaction between the analyte and titrant

To avoid affecting the volume required to reach equivalence (correct)

To prevent the appearance of unwanted colors in the solution

How can it be determined that titres are concordant in a titration process?

By measuring the temperature of the solution

When the pink color appears immediately

By ensuring there are no drops left in the burette

When the differences between initial and final burette readings are within a certain range (correct)
