1) When 0.0044 moles of a weak acid are dissolved in enough water to make 0.500 L, the pH of the resulting solution is 5.01. Calculate Ka.

2) Phenol (C6H5OH, also called carbolic acid) has a pKa of 9.89. It is used to preserve body tissues and is quite toxic. Calculate the percent ionized in 0.0399 M phenol--a dilute solution.

3) Calculate the percent ionized in 2.63x10-6 M phenol--a very dilute solution.
