Chapter 16.10, Problem 5CP

The diagrams represent solutions of three salts $\text{NaX }\left(\text{X = A, B, or C}\right)$. Arrange the three X^- anions in order of increasing base strength. (The ${\text{Na}}^{\text{+}}$ ions are not shown.)

$\begin{array}{l}\text{a)}\hfill \\ {\text{A}}^{\text{-}}{\text{< B}}^{\text{-}}{\text{< C}}^{\text{-}}\hfill \\ \text{b)}\hfill \\ {\text{A}}^{\text{-}}{\text{< C}}^{\text{-}}{\text{< B}}^{\text{-}}\hfill \\ \text{c)}\hfill \\ {\text{B}}^{\text{-}}{\text{< A}}^{\text{-}}{\text{< C}}^{\text{-}}\hfill \\ \text{d)}\hfill \\ {\text{C}}^{\text{-}}{\text{< B}}^{\text{-}}{\text{< A}}^{\text{-}}\hfill \\ \text{e)}\hfill \\ {\text{C}}^{\text{-}}{\text{< A}}^{\text{-}}{\text{< B}}^{\text{-}}\hfill \end{array}$
