Question

When determining the standard reduction potential of a substance by using a standard hydrogen electrode as a reference, the standard reduction potential will always be equal to:______.
ta. he reduction potential for the standard hydrogen electrode.
b. one-half the cell potential.
c. the overall cell potential.
d. impossible to predict.

Answer 1

Answer:

the overall cell potential

Explanation:

We must bear in mind that the standard hydrogen electrode is a reference electrode whose electrode potential has been arbitrarily set at 0 V.

The standard hydrogen electrode consists of hydrogen ion solution and hydrogen gas together with a platinum electrode.

The overall cell potential is the reduction potential of the substance being determined using the standard hydrogen electrode as a reference electrode since its electrode potential is set at zero volts.
