Adding KI(aq) to a solution containing Cu2+(aq) causes a reaction to take place, which produces purple-brown iodine and a white precipitate of the highly insoluble copper(I) iodide.
i) construct a balance equation for this reaction
ii) using appropriate E node value, explain why it is expected that this redox reaction will not occur
iii) suggest a possible reason why the reaction in fact occur
