A chemistry student is asked to find the standard cell potential for the redox reaction: Mg(s) | Mg²⁺(aq, 0.1 M) || Cu²⁺(aq, 0.01 M) | Cu(s) Given that the standard potential for the reduction of Mg²⁺ is -2.37 V and for the reduction of Cu²⁺ is +0.34 V. The student should show how to calculate the cell potential and determine if the reaction will proceed spontaneously or not.
