A buffer solution contains a weak acid, HA, and its conjugate base, $${\mathrm{A}}^{?}$$. The buffer solution has a $$\mathrm{pH}$$ of $$5.59$$, and the weak acid has a $$\mathrm{p}{K}_{\mathrm{a}}$$ of $$5.13$$ Without performing a calculation, determine the relationship between the concentration of the weak acid and the concentration of the conjugate base in this buffer solution? $$[\mathrm{HA}]=\left[{\mathrm{A}}^{?}\right]$$ The relationship between [HA] and $$\left[{\mathrm{A}}^{?}\right]$$cannot be determined. $$\begin{array}{l}[\mathrm{HA}]>\left[{\mathrm{A}}^{?}\right]\\ [\mathrm{HA}]<\left[{\mathrm{A}}^{?}\right]\end{array}$$
