Question

define standard half cell potential​

Answer 1

Half-cell potential refers to the potential developed at the electrode of each half cell in an electrochemical cell. In an electrochemical cell, the overall potential is the total potential calculated from the potentials of two half cells.

To get around this problem, scientists have agreed to measure all voltages against a standard hydrogen electrode (SHE), for which the standard half-cell potential is defined as 0 V
