Au³⁺ metal ion is reduced in the Au/Cr cell and Co²⁺ metal ion is reduced in the Co/Zr cell
<h3>What is a voltaic cell?</h3>A voltaic cell is a cell that generates electricity by a spontaneous redox reaction.
It is an electrochemical cell, also known as a galvanic cell and
Electrical energy is created by converting chemical energy.
Examples of voltaic cells include the dry cell, nickel-cadmium cell, lead storage cell, and fuel cells.
The half-cell reactions for each cell are given by
; E° = 1.50 V
; E° = –0.74 V
; E° = –0.28 V
E° = –0.76 V
Thus, Au³⁺ is reduced in the Au/Cr cell and Co²⁺ is reduced in the Co/Zr cell
