Refer to the stability of [Co(NH 3 ) 6 ] 3+ (aq) (a) Verify that E cell

Question:

Refer to the stability of [Co(NH₃)₆]³⁺(aq)

(a) Verify that E°_cell reaction (24.12) is +0.59 V.

(b) Calculate [Co³⁺] in a solution at equilibrium that has a total concentration of cobalt of 0.1 M and [NH₃] = 0.1 M.

(c) Show that for the value of [Co³⁺] calculated in part (b), reaction (24.12) will not occur. Assume a low, but reasonable, concentration of Co²⁺ (say, 1 x 10^–⁴ M) and a partial pressure of O₂(g) of 0.2 atm.

Reaction (24.12)

4Co3+(aq) +2H,O(1) 4 Co+ (aq) + 4H+ (aq) + O(g) Ecell = +0.59 V (24.12)
