CORRECT-INCORRECT STATEMENT
\( S_{1} \) : In the acid-base titration involving strong base and weak acid, methyl red can be used as an indicator.
\( \mathbf{S}_{2} \) : Methyl red changes its colour in the \( \mathrm{pH} \) range 4.2 to 6.3 .
\( \mathrm{S}_{3} \) : In a titration of weak acid with strong base, the \( \mathrm{pH} \) at the half equivalence point is \( \mathrm{pK}_{\mathrm{a}} \).
