Question

Consider the titration of a 22.0 mL sample of 0.110 molL−1 CH3COOH (Ka=1.8×10−5) with 0.125 molL−1 NaOH. Determine each quantity:

Part A

the initial pH

pH =

2.85

Part B

the volume of added base required to reach the equivalence point

V =

19.4

mL

Part C

the pH at 4.0 mL of added base

pH =

4.16

Part D

the pH at one-half of the equivalence point

pH =

4.74

Part E

the pH at the equivalence point

pH =

8.76

Part F

the pH after adding 6.0 mL of base beyond the equivalence point

**I only need the answer to PART F
