Interpretation:
The given
Concept introduction:
Oxidation number method to balance ionic equation in basic solution involve:-
- Assign the oxidation number to each element.
- Check which element is oxidized and which element is reduced.
- Check the change in oxidation number for the elements which are oxidized and reduced.
- Balance the change in oxidation number by adjusting the coefficients in the equation.
- Then add enough hydroxyl ions to balance the charge and water molecules to the equation to balance hydrogen atoms on both sides.
Answer to Problem 22PP
Explanation of Solution
The given redox reaction is:
Assigning the oxidation number-
The oxidation numbers of atoms shows that
Change in oxidation number of
Change in oxidation number of
Thus adjusting the coefficients:
Balancing the atoms:
Now adding hydroxyl ions on right side of equation to balance negative charge
Adding water to left side:
Thus the balanced redox equation is:
