Exp5 - Determining the Dissociation of a Weak Acid using pH Measurement 16. (3 pts) A solution was made by adding 30.00 mL of 0.215 M NaOH solution to 25.00 mL of 0.445M HA solution. This mixture was diluted to 250.00 mL. The pH of this solution was 5.83. Calculate the dissociation constant, Ka. HA (aq) + H2O(l) = H30 (aq) + A (aq)
