What is the pH of 0.015 M aqueous benzoic acid? (Ka of C5H6CO2H = 6.3 Ă— 10^-5) Which of these is the answer? a. 1.82 b. 3.03 c. 4.20 d. 6.02 e. 12.18
Added by Kari J.
Step 1
\[ [\text{H}^+] = \sqrt{6.3 \times 10^{-5} \times 0.015} \] \[ [\text{H}^+] = \sqrt{9.45 \times 10^{-7}} \] \[ [\text{H}^+] = 9.72 \times 10^{-4} \] Show more…
