Choice of Weak Acid for a Buffer Which of these compounds would be the best buffer at $\mathrm{pH} 5.0$ : formic acid $\left(\mathrm{p} K_{\mathrm{a}}=3.8\right),$ acetic acid $\left(\mathrm{p} K_{\mathrm{a}}=4.76\right),$ or ethylamine $\left(\mathrm{p} K_{\mathrm{a}}=\right.$ 9.0)? Briefly justify your answer.
