(a)
Interpretation:
The given
Concept introduction:
Oxidation number method to balance ionic equation in acidic 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 hydrogen ions and water molecules to the equation to balance hydrogen atoms on both sides.
Answer to Problem 79A
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:
Now adding hydrogen ions on right side of equation to balance negative charge
Adding water to left side:
(b)
