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