Question

An electro chemical cell composed of zinc and magnesium electrodes immersed in solutions of respective divalent ions was setup. For a 0.7M concentration of Mg2+, a cell potential of 1V is recorded.

(a) Write the half life reactions and respective potential. What is the potential difference for the whole reaction?

(b) Calculate the concentration of Zn2+ ions if the temperature is 37 degrees Celsius. Setup the equation clearly and show all calculation steps.
