1. This problem will be done for one of the two buffers you made. (Your lab partner should do these calculations for the other one.) a. What is the ratio of A/HA in your buffer after you adjusted its PH to the required value? Pf=PKQ+log([A]/[HA]) 7.52.13+log([A]/[HA])5 b. How many micromoles of Aand HA are present in the solution? c. If you now add 3mL of 1MNaOH, will you still have a valid buffer? 1. This problem will be done for one of the two buffers you made.
