Chemistry

Consider the titration of a 33.0 mL sample of 0.175 M HBr with0.210 M KOH. Determine each of the following:

Part A the initial pH

Express your answer using three decimal places. pH =

Part B the volume of added base required to reach theequivalence point

Express your answer in milliliters. V =

Part C the pH at 11.0 mL of added base

Express your answer using three decimal places. pH =

Part D the pH at the equivalence point

Express your answer as a whole number. pH =

Part E the pH after adding 5.0 mL of base beyond the equivalencepoint

Express your answer using two decimal places pH =
