Kb of aniline (C6H5NH2) is 4.3x10-10

(1) Setup an ICE chart

(2) Setup Kb expression

$\overline{){{\mathbf{K}}}_{{\mathbf{b}}}{\mathbf{=}}\frac{\mathbf{products}}{\mathbf{reactants}}{\mathbf{=}}\frac{\mathbf{\left[}{\mathbf{OH}}^{\mathbf{-}}\mathbf{\right]}\mathbf{\left[}{\mathbf{C}}_{\mathbf{6}}{\mathbf{H}}_{\mathbf{5}}{{\mathbf{NH}}_{\mathbf{3}}}^{\mathbf{+}}\mathbf{\right]}}{\mathbf{\left[}{\mathbf{C}}_{\mathbf{6}}{\mathbf{H}}_{\mathbf{5}}{\mathbf{NH}}_{\mathbf{2}}\mathbf{\right]}}}$

Solving for x = [OH-]
