Question:

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:(a) [Cu+] = 0.050 M, [Ni+] = 1.40 M (b) Pci 320 torr (c) [I]= 0.0010 M, Pcl = 0.300 atm, [C1-] = 0.60 M

Exercise 18.43

Use the standard reduction potentials in Table18.1 to find

(a) A metal ion that reduces Ni2+.

(b) A metal ion that can oxidize Cu.

(c) A metal ion that is reduced by Cr2+ but not H2.
