Question

Quizplus · Accepted Answer

The sodium salt of acetylsalicylic acid is a basic salt. To find the pH, we first calculate the Kb using the relation Kw = Ka * Kb, where Kw = 1.0 × 10^-14. Then, use the Kb to find the pOH and convert it to pH. The calculation shows that the pH is approximately 8.3.
