Question

1. Let's pretend you will be titrating ~0.1M acetic acid (HCH;CO2, a weakacid) with -0.5M of NaOH (a strong base). The K, of acetic acid is 1.8 x 10-5and the pka of acetic acid is 4.8. You start with 50ML of acetic acid a) (T/l and A) What is the pH of 0.1M acetic acid? [2 marks] b) (T/l and A) What is the pH after you add 6 mL of the 0.5M NaOH? [4marks] c) (T/l and A) At what volume do you expect to reach your equivalence point?[2 marks] d) (T/l and A) At what pH do you suspect you'll be at when your equivalence point is reached? [4 marks]
