While 0.0044 moles of a weak acid are dissolved in enough water to make 0.500 L, the pH of the resulting solution is 6.10. Calculate Ka.
Phenol (C6H5OH, as well called carbolic acid) has a pKa of 9.89. It is utilized to preserve body tissues and is quite toxic. Compute the percent ionized in 0.0849 M phenol--adilute solution.
Compute the percent ionized in 6.19x10-6 M phenol--a very dilute solution.
