Answer to Question 1

ANS: A
The phosphate buffer solution in the pH electrode has a pH of 6.84.

Answer to Question 2

ANS: C
Oxygen from the blood sample diffuses across the semipermeable plastic membrane into the KCl solution and reacts with the platinum cathode, altering the conductivity of the electrolyte solu-tion. The platinum cathode donates electrons, which reduce oxygen to produce hydroxyl ions.
