We are being asked the K_{b} and pK_{b} of the conjugate base that has a K_{a} of 3.1x10^{-9}

We will use the following equations to solve this problem:

$\overline{){{\mathbf{K}}}_{{\mathbf{b}}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}\frac{{\mathbf{K}}_{\mathbf{w}}}{{\mathbf{K}}_{\mathbf{a}}}}\phantom{\rule{0ex}{0ex}}\overline{){{\mathbf{pK}}}_{{\mathbf{b}}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}{\mathbf{-}}{{\mathbf{logK}}}_{{\mathbf{b}}}}$

What is the K_{b} of the conjugate base that has a K_{a} of 3.1x10^{-9}? Convert the K_{b} to pK_{b }and enter that into the field.
