A 30.0-mL volume of 0.50 M CH3COOH (Ka=1.8x10^-5) was titratedwith 0.50 M NaOH. Calculate the pH after addition of 30.0 mL ofNaOH
13. Consider the titration of a 20.00 mL sample of 0.105 M CH3COOH (acetic acid) with 0.125 M NaOH. The Ka for acetic acid is 1.8 Ã 10-5. Calculate the pH after 10.00 mL of NaOH is added. The volume needed of base to reach the equivalence point/end point is 16.80 mL. (A) pH = 4.74 (B) pH = 4.91 (C) pH = 4.57 (D) pH = 8.75
