The different colours of litmus in acidic, neutral and basic solutions are, respectively.

The suitable indicator for the titration of a strong acid and a weak base is:

Phenolphthalein is not a suitable indicator for the titration between which of the following?

Which indicator works in the $pH$ range of $8 - 9.8$?

The pink colour of phenolphthalein in an alkaline medium is due to -

If a very small amount of $HPh$ (phenolphthalein) is added to a $0.1 \ M$ aqueous solution of $CH_3COONa$,the fraction of the indicator that exists in the colourless form is:
$[K_b(CH_3COO^{-}) = 10^{-9}, pK_a(HPh) = 9.6, \log 2 = 0.3]$
