Answer to Problem 56A

The given equation is not balanced because electrons lost by Fe is not equal to gained by Ag+

Explanation of Solution

The given equation is:

Fe+Ag+Fe+2+Ag

Oxidation half reaction is:

FeFe+2+2e

Reduction half reaction is:

Ag++eAg

To balance the reaction, reduction half reaction is multiplied by 2 and then added to oxidation half reaction:

Fe+2Ag+Fe+2+2Ag

Conclusion

A redox reaction is balanced if number of atoms of each element and net charge on both sides is equal. The number of electrons lost is equal to number of electrons gained.
