Problem

The indicator HInd is used in a titration between an acid and base. Which statement about the dissociation of the indicator, HInd, is correct?

HInd(aq)	$\rightleftharpoons$	H $^+$ (aq)	$+$	Ind $^-$ (aq)
colour A				colour B

a. In a strongly alkaline solution, colour B would be observed. b. In a strongly acidic solution, colour B would be observed. c. [Ind

^{-}

] is greater than [HInd] at the equivalence point. d. In a weakly acidic solution colour B would be observed.
