QUDO: 99 1) What will happen to the voltage of the cell in the we do question if the cell is allowed to run? lustily your selection • Stays the same Decreases Increases 2) A student tried to make a thermodynamically spontaneous cell at 298.composed of 100 ml of 1,00m Mga in one beaker with a magnesium electrode and 100 mL of 1,00 MM 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 AP Mg Mg? AB=0.71 V The student ran out of magnesium nitrate and could only make 100 miofa Mg solution with a concentration of 0.75 M. What effect, if any, will this have on their cell potential? Explain. 3) A different student tried to make a thermodynamically spontaneous cell at 298 K composed of 500 ml beaker with an aluminum electrode. The beakers are connected with a porous dise and the electrodes 661,00 M Mga in one beaker with a magnesium electrode and 100 mL of 1.00 MAP in another are connected with a wire connected to a voltmeter: A+ Mg→ Mga+ Al. E = +0.71 V The student ran out of magnesium nitrate and could only make 100 mL of a Mg:- solution with a concentration of 0.75 M. This student decided to make the concentration of both solutions the same, and used 100 ml of 0.75 M of the AP solution What effect, if any, will this have on their cell potential? Explain. Cell potential will not chance and remain the same. 4) A third student made the same thermodynamically spontaneous cell at 298 K composed of 100 mlof Mg) in one beaker with a magnesium electrode and 100 mL of APP 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: Al) + Mg Mg2+ Alo E = +0.71 V This student found another bottle of magnesium nitrate and decided to make their cell using 100 mL of a Mga solution with a concentration of 2.00 M. This student decided to make the concentration of both solutions the same, and used 100 mL of 2.00 M of the All-solution What effect, if any, will this have on their cell potential? Explain. *a Is there an advantage to using higher concentrations? Explain
