Homework Question 8.16 Determine (or estimate) the pKa of an acid with an acidity constant K= 1 x 10^-6. Values in Table 9.3 may be helpful.
Homework Answers
We know that;
pKa = - log Ka
pKa = - log (1*10^-6) = 6
Hence,
pKa = 6 ....Answer
Let me know if any doubts.

Determine the pH of the solution (to 2 decimal points) after the
addition of 11.7 mL of 6.14 M hydrochloric acid (HCl) to 624 mL of
0.735 M phenylamine (aniline)
(C6H5NH2).
Assume that the volumes are additive and that the 5% approximation
is valid.
