Q3. Weak Acid Strong Base Titration (Medium)
You are provided with 100ml of 0.016M HOCl (Ka = 3.5 x 10-
8) in the flask and 0.04M NaOH solution in the burette.
Calculate the pH when
A- No NaOH is added
B- 10ml of NaOH is added
C- Titration is at half equivalence point and the amount
of NaOH used
D- Titration is at equivalence point and the amount of
NaOH used
E- 50ml of NaOH is added
