Academics

A voltaic cell consists of a Zn/Zn2+ half-cell and a Ni/Ni2+half-cell at 25 °C. The initial concentrations of Ni2+ and Zn2+are 1.80 M and 0.120 M , respectively. The volume of half-cells is the same.

1. What is the initial cell potential? ANSWER: 0.56 v

2. What is the cell potential when the concentration of Ni2+ has fallen to 0.600 M ? ANSWER: 0.600 M

3. What is the concentrations of Ni2+ when the cell potential falls to 0.46 V ?

4. What is the concentration of Zn2+ when the cell potential falls to 0.46 V ?
