Answer

-\log(K_a) $$

~Mataa🫶🏽, let's knock this out.

Step 1: Calculate the $\text{pK}_a$ from the given $\text{K}_a$ value for $\text{HCO}_3^-$ . The $\text{K}_a$ for $\text{HCO}_3^-$ is $4.7 \times 10^{-11}$ . $pK_a = -\log(K_a)$ $pK_a = -\log(4.7 \times 10^{-11})$ $pK_a \approx 10.3279$

Step 2: Use the Henderson-Hasselbalch equation to find the ratio of the conjugate base
