Ag+(aq) + e- rightarrow Ag(s) Fe2+(aq) + 2e- rightarrow Fe(s) Ag+(s) rightarrow Ag+(aq) + e- Fe+(s) rightarrow Fe2+(aq) + 2e - A redox reaction is found to be spontaneous at standard conditions. Which set of thermodynamics properties is true for this reaction? Redox equations are often so complex that fiddling with coefficients to balance chemical equations doesn’t always work well. Chemists have developed an alternative method (in addition to the oxidation number method) that is called the ion-electron (half-reaction) method. In the ion-electron method, the unbalanced redox equation is converted to the ionic equation and then broken […]

We learnt that the E value for the reaction Cu2+ (aq) + 2I- (aq) --> CuI (s) + 1/2 I2 (aq) is negative so the reaction is not supposed to be feasible. However, the reaction actually occurs and we were explained that this is because the precipitation of CuI removes Cu+ ions from the solution and so the...
