Will magnesium metal displace Al 3+ (aq)ion from an aqueous solution? Mg 2+ (aq)+ 2 e - → Mg(s)E° = -2.356 V Al 3+ (aq)+ 3 e - → Al(s)E° = -1.676 V

The cell potential is positive, indicating that the reaction is spontaneous. Therefore, magnesium metal will displace Al3+(aq) ion from an aqueous solution.

Question 59

Multiple Choice

Will magnesium metal displace Al³⁺(aq) ion from an aqueous solution?
Mg²⁺(aq) + 2 e^- → Mg(s) E° = -2.356 V
Al³⁺(aq) + 3 e^- → Al(s) E° = -1.676 V

A) No,since E°_cell is negative.
B) Yes,since E°_cell is negative.
C) No,the reverse reaction is spontaneous.
D) Yes,since E°_cell is positive.
E) No,the system is at equilibrium.
