We’re being asked to calculate the H of a 4.6 M aniline solution.
Since aniline has a low Kb value, it’s a weak base. Remember that weak bases partially dissociate in water and that bases accept H+ from the acid (water in this case). The dissociation of aniline is as follows:
aniline (aq) + H2O(l) ⇌ OH–(aq) + aniline-H+(aq); Kb = 3.8x10-10
Calculate the pH of a 4.6 M solution of aniline (C6H5NH2; Kb= 3.8x10-10)
