2) A student tried to make a thermodynamically spontaneous cell at 298 K composed of 100. mL of 1.00 M Mg2+ (aq) in one beaker with a magnesium electrode and 100. mL of 1.00 M Al3+ (aq) in another beaker with
an aluminum electrode. The beakers are connected with a porous disc and the electrodes are
connected with a wire connected to a voltmeter:
Al3+ (aq) + Mgs → Mg2+ (aq) + Al(s) E° = +0.71 V
The student ran out of magnesium nitrate and could only make 100. mL of a Mg2+ solution with a
concentration of 0.75 M. What effect, if any, will this have on their cell potential? Explain.
