We’re being asked to determine the approximate Ka for acid HX based on the titration curve given.
Recall the different parts of a titration curve:
Consider a titration in which NaOH is being added to a flask which originally contains 1.0 liter of 1.0 M HX. The titration curve for this process is shown below.
Based on this data, what is the approximate Ka for acid HX?
A. 1 x 10-10
B. 1 x 10-7
C. 1 x 10-6
D. 1 x 10-5
E. 1 x 10-3
