Problem 99P

If a strip of magnesium metal is dipped into a solution containing silver ions, does a spontaneous reaction occur? If so, write the two half-reactions and the balanced overall equation for the reaction.

Step-by-Step Solution:
Step 1 of 3

Step-1

Magnesium metal is dipped into a solution containing silver ions,  spontaneous reaction occurs. According to the classification , magnesium is a member of the third class and silver is a member of the first, so magnesium should be more readily oxidized than silver. The magnesium should be oxidized to Mg2+ (aq) and Ag + (aq) should be reduced to silver metal when magnesium added to silver nitrate solution.

Step-2

As the ions are of different charge,conservation of charge can be achieved only by making two silver ions react with each magnesium atom.

The two half reactions are,

...

Mg2+ + 2 e-  Mg
