Question

What is the pH at equivalence point in the titration of 0.1 M CH3COOH and 0.1 M NaOH? (Ka for acetic acid is 5 1.8 10  ) 1) 7 2) Between 7 and 8 3) Between 8 and 9 4) Between 6 and 7

Answer 1

TIP

For titration means salt hydrolysis

Explanation:

pH = 1/2(pKw +pKa +logc)

    =8. something

Between 8 and 9
