Interpretation:
For the given titration curves, the suitable indicator has to be selected for each of them and the color change observed in the end point has to be given.
Concept introduction:
There are primarily four types of acid-base titrations –
- Strong base vs strong acid
- Strong base vs weak acid
- Weak base vs strong acid
- Weak base vs weak acid
Equivalence point ensures the titration reaction becomes completed and at this point the number of moles of titrant and the number of moles of analyte remain equal. We cannot see the completion of titration reaction – the titrant and the analyte becoming equal in stoichiometric proportion , hence we use a chemical compound called indicator called which indicates the end of the reaction by color change. The end point refers to the color change and indicates equivalence point has been reached.
