Pyridine is a weak base that is used in the manufacture of pesticides and plastic resins. It is also a component of cigarette smoke. Pyridine ionizes in water as follows: C5H5N(aq) + H2O (l) C5H5NH+ (aq) + OH- (aq) The pKb of pyridine is 8.75. What is the pH of a 0.180 mol L^-1 solution of pyridine? Express the pH numerically to two decimal places.
