August 4, 2017A test electrode contains a solution of ubiquinone, with both the fully oxidized and fully reduced forms, at 1 M concentration each. A circuit is formed from this electrode using a KCL solution salt bridge with a standard hydrogen electrode (25 degrees Celsius, 1 ATM H2, 1 M H+ . When this circuit is complete, a current of electrons pass to the ubiquinone test cell at +0.045 volts.
a) What is the standard reduction potential (E o’ ) of ubiquinone?
b) Which has a higher standard reduction potential, ubiquinone or oxygen?
