2. A sample of the weak acid boric acid (H, BO2) is titrated with potassium hydroxide. The first and second steps of this reaction were quantitative.
a) Draw a pH curve with title and labeled axes and write the B-L neutralization for
each of the endpoints. (2 endpoints)
I
b) If the titration were stopped halfway between the first and second endpoints, what
entities would be present in the flask?
c) Using your answer from part b), which entities would be considered amphiprotic?
Which entities would form the buffer?
