The pyridinium ion (C5H4NH*) is a weak acid (Ka = 5.60 x 10-6). Calculate the pH of a solution that results from adding 3.79 mL of 0.167 M KOH to 19.7 mL of 0.134 M C5H4NH* solution. (the answer should be entered with 3 significant figures; do not enter units; give answer in normal notation-examples include 1.23 and 120. and -123 and 123. and 12.3)
