In the hydrolytic equilibrium \( \mathrm{A}^{-}+\mathrm{H}_{2} \mathrm{O} \rightleftharpoons \mathrm{HA}+\mathrm{OH}^{-} \)
\( \mathrm{P} \)
\( \mathrm{K}_{\mathrm{a}}=1.0 \times 10^{-5} \). The degree of hydrolysis of \( 0.001 \mathrm{M} \)
W
solution of the salt is:
(1) \( 10^{-3} \)
(2) \( 10^{-4} \)
(3) \( 10^{-5} \)
(4) \( 10^{-6} \)
