Pyruvic acid is a weak acid. Which of following is a likely pH for an aqueous solution of sodium pyruvate?
correct answer: 8.0
kaplan's Reason:
The salt of a weak acid will hydrolyze in aqueous solution according to the following generalized equilibrium expression:
A- + H2O ---> HA + -OH
but, I don't get why by looking the above reaction, I would figure out the correct pH is 8?
If you are a acid base expert, please explain. Thanks!
