Question 1

A concentration cell is constructed using two Ni electrodes with Ni2+ concentrations of 1.0 M and 1.00 × 10–4M in the two half-cells. The reduction potential of Ni2+ is –0.23 V. Calculate the potential of the cell at 25°C.

◦ –0.368 V
◦ +0.132 V
◦ –0.132 V
◦ +0.118 V
◦ +0.0592 V

Question 2

A concentration cell is constructed with copper electrodes and Cu2+ in each compartment. In one compartment, the [Cu2+] = 1.0 10–3M and in the other compartment, the [Cu2+] = 2.0 M. Calculate the potential for this cell at 25°C. The standard reduction potential for Cu2+ is +0.34 V.

◦ 0.44 V
◦ –0.44 V
◦ 0.098 V
◦ –0.098 V
◦ 0.78 V
