Question
Nicotine is dibasic (in other words, it is a base but follows a similar pattern to a diprotic acid). If the generic aqueous equilibrium reactions with corresponding pKb values are provided below (where nicotine is B), answer the subsequent questions.
B(aq) + H20 (l) ---> <--- BH^+ (aq) + OH^- (aq). pkKb = 6.0
BH^+ (aq) + H20 (l) ---> <--- BH2 ^2+ (aq) + OH^- (aq). pkKb2 = 10.9.0
A) WHAT IS the value of kb2?
b) What is the pH of the resulting solution at equilibriu,?
c) using either only the pkb value or the kb value, explain why the pH doesnt change much after the first reaction?
Initial concentration of B (aq) is 0.43 M
