The colour change of an indicator in acid base titrations is given below

Which of the following statement is correct?

Which of the following statement is correct?
- Correct answerAIn a strong alkaline solution colour Y will be observed
- BIn a strong acidic solution colour Y will be observed
- CConcentration of is higher than that of HIn at the equivalence point
- DIn a strong alkaline solution colour X is observed
Solution
It is an acidic indicator therefore will remain in ionized form in strong alkaline solution (opposite ion effect) so it will show the colour due to which is colour Y.
Hence, the correct answer is option: 'A'.
