The $\mathrm{p}{K}_{\mathrm{a}}$ value for ${\mathrm{CH}}_3\mathrm{COOH}$ is 4.74 . Would a buffer prepared from ${\mathrm{CH}}_3\mathrm{COOH}$ and ${\mathrm{CH}}_3\mathrm{COONa}$ with a pH of 2.94 be considered to be an effective buffer? A buffer in which the mole ratio of ${\mathrm{CH}}_3\mathrm{COONa}$ to ${\mathrm{CH}}_3\mathrm{COOH}$ is 1.8 has a pH of 4.99. Would this buffer solution have a greater capacity for added acid $\left({\mathrm{H}}_3{\mathrm{O}}^{+}\right)$or added base $\left({\mathrm{OH}}^{?}\right)$?
