need help with titration (buffer system) question.

Which of the following statements are incorrect?
a) pKw = 14
b) pKw = pKa + pKb
c) Kw = 1 x 10-14
d) Kw = Ka + Kb

1. Only b is incorrect
2. Only d is incorrect
3. Both c and d are incorrect
4. Both a and b are incorrect
5. All are correct

not sure how to even attempt this question, so any help would be appreciated!!

  2. Yes, d is the only incorrect statement.
    Kw = Ka*Kb and not Ka + Kb
