Interpretation: Whether the given
Concept Introduction: Whether a metal can reduce other metals from its solution or not can be determined from its reduction electrode potential. The metal with a high reduction electrode potential cannot reduce the metal with a low reduction electrode potential.
Explanation of Solution
The given redox reaction is as follows:
The two half-reactions can be represented as follows:
Here, the reduction of Al and oxidation of Mg take place.
Now, the reduction electrode potential values of Al and Mg are as follows:
Here, the reduction electrode potential for Al is more than Mg; thus, Al undergoes reduction and Mg undergoes oxidation.
Thus, the given reaction is spontaneous.
