(a)
Interpretation:
The following unbalanced reaction takes place in acidic solution
To write the balanced equation
Concept Introduction:
Here are the rules to
Determine the oxidation numbers of the elements and write the oxidation and reduction half equation.
Balance the atoms of elements other than O and H. Use H2O to balance O, H+ to balance H, electrons to balance the charges. Equalize the number of electrons on both the half reactions and then add the half reactions.
(b)
Interpretation:
