The colour change of an indicator HIn in acid base titrations is given below Which of the following statement is correct?

Options

  1. AIn a strong alkaline solution colour Y will be observed
  2. BIn a strong acidic solution colour Y will be observed
  3. CConcentration of I n - is higher than that of HIn at the equivalence point
  4. DIn a strong alkaline solution colour X is observed

Correct answer

A. In a strong alkaline solution colour Y will be observed

Step-by-step 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 I n a q - which is colour Y.
