Two voltaic cells are to be joined so that one will run the other as an electrolytic cell. In the first cell, one half-cell has
stiks02 [169]

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

Au^{3+}(aq) + 3e^- \rightarrow Au(s) ; E° = 1.50 V

Cr^{3+}(aq) + 3e^- \rightarrow Cr(s) ; E° = –0.74 V

Co^{2+}(aq) + 2e^- \rightarrow Co(s) ; E° = –0.28 V

Zn^{2+}(aq) + 2e^- \rightarrow Zn(s) E° = –0.76 V

Thus, Au³⁺ is reduced in the Au/Cr cell and Co²⁺ is reduced in the Co/Zr cell
