Calculate the potential of a platinum electrode immersed in a solution that is
(a) 0.0513 M in K₄Fe(CN)₆ and 0.00589 M in K₃Fe(CN)₆.
(b) 0.0300 M in FeSO₄ and 0.00825 M in Fe₂(SO₄)₃.
(c) Buffered to a pH of 4.85 and saturated with H₂ at 1.00 atm.
(d) 0.1455 M in V(OH)₄ ⁺, 0.0802 M in VO²⁺, and 0.0800 M in HClO₄.
(e) Prepared by mixing 50.00 mL of 0.0507 M Ce(SO₄)₂ with an equal volume of 0.100 M FeCl₂ (assume solutions were 1.00 M in H₂SO₄, and use formal potentials).
(f) Prepared by mixing 25.00 mL of 0.0832 M V₂(SO₄)₃ with 50.00 mL of 0.00628 M V(OH)₄ ⁺ and has a pH of 1.00.
(g) Draw a schematic diagram for each of the half-cells described in (a) through (f).
