Determine the pH of a 0.18 mol L^-1 H₂CO₃ solution. Carbonic acid is a diprotic acid whose K_a₁ = 4.3 × 10^-7 and K_a2 = 5.6 × 10^-11. A) 11.00 B) 10.44 C) 5.50 D) 4.31 E) 3.56

Question

Quizplus · Accepted Answer

The pH of a diprotic acid like H2CO3 is primarily determined by the first dissociation constant (Ka1). Using the formula pH = -log[H+], where [H+] is approximately equal to the square root of (Ka1 * concentration), we find the pH to be around 3.56.
