Consider the titration of a 32.0 mL sample of 0.180 molL−1 HBr with 0.210 molL−1 KOH. Determine each quantity:

Part A

the initial pH

Express your answer using three decimal places.

pH =

Part B

the volume of added base required to reach the equivalence point

V =

mL

Part C

the pH at 12.0 mLmL of added base

Express your answer using three decimal places.

pH =

Part D

the pH at the equivalence point

Express your answer using two decimal places.

pH =

Part E

the pH after adding 5.0 mL of base beyond the equivalence point

Express your answer using two decimal places.
