What is the pK value for the following equilibria involving the neutralization of piperidine (C5H11N) with acid? (The Kb of piperidine is Kb = 1.3 x 10-3)
C5H11N + H3O+ <----> C5H11NH+ + H2O
Attempt at a solution: I solved for Ka by taking 1E-14/Kb
then I took -log(ka)
which I got to equal 2.89
this answer is wrong.. and I don't see how else to do the problem! any help would be GREATLY appreciated since i've been stuck on this problem for hours
