CORRECT-INCORRECT STATEMENT
\( \mathbf{S}_{1} \) : The \( \mathrm{pH} \) of a solution made by dissolving 1 mole each of \( \mathrm{HCl}, \mathrm{NaOH} \) and \( \mathrm{CH}_{3} \mathrm{COONH}_{4} \) in the same beaker is 7 if \( \mathrm{pK}_{\mathrm{a}}\left(\mathrm{CH}_{3} \mathrm{COOH}\right)=\mathrm{pK}_{\mathrm{b}}\left(\mathrm{NH}_{3}\right) \).
\( \mathbf{S}_{2} \) : Phenolphthalein is used as an indicator in the titration of \( \mathrm{NH}_{3} \) with \( \mathrm{HCl} \).
\( \mathbf{S}_{3} \) : Ammonia acts as a base when dissolved in water.
