Chapter 18, Problem 18.61QE

Calculate the potential for each of the voltaic cells in Exercise 18.43 when the concentrations of the soluble species and gas pressures are as follows:

1. (a) [Cu²⁺] = 0.050 M, [Ni²⁺] = 1.40 M
2. (a) $P_{\text{C}}{}_{{\text{l}}_{\text{2}}}=\text{ 32}0\text{ torr}$
3. (b) $\left[{\text{I}}^{-}\right]=0.00\text{1}0M,P_{{\text{Cl}}_{\text{2}}}\text{= }0.\text{3}00\text{ atm},\left[{\text{Cl}}^{\text{-}}\right]\text{ = }0.\text{6}0M$
4. (a) Cu²⁺ (aq) + Ni(s) → Cu(s) + Ni²⁺ (aq)
5. (b) 2Ag(s) + Cl₂(g) → 2AgCl(s)
6. (c) Cl₂(g) + 2I⁻(aq) → 2Cl⁻(aq) = I₂(s)
