The pH of 0.1M pyruvic acid will be _____?

The pH of 0.1M pyruvic acid will be _____?

Explanation
  • Pyruvic acid (CH₃COCOOH) is a weak acid with a pKa of around 2.5,
  • This meaning it partially ionizes in water.
  • Using the Henderson-Hasselbalch equation, the pH of a 0.1M solution of pyruvic acid is approximately 4.5.
