Which of the following is not correct about the
\( \mathrm{P} \)
percentage ionization of \( \mathrm{BOH} \) ?
(1) \( \frac{\mathrm{K}_{\mathrm{w}}\left[\mathrm{H}^{+}\right]}{\mathrm{K}_{\mathrm{b}}+\mathrm{K}_{\mathrm{w}}} \)
(2) \( 100 \times \sqrt{\frac{\mathrm{K}_{\mathrm{b}}}{\mathrm{C}}} \)
(3) \( \frac{100}{1+10^{\left(\mathrm{pK}_{\mathrm{b}}-\mathrm{pOH}\right)}} \)
(4) \( \frac{\mathrm{K}_{\mathrm{b}} \times 100}{\mathrm{~K}_{\mathrm{b}}+\mathrm{OH}^{-}} \)
