(a)
Interpretation: The given half-reaction which take place in acidic solution needs to be balanced.
Concept Introduction: By a transfer of electrons,
(a)
Answer to Problem 25A
Balanced half-reaction is-
Explanation of Solution
The given half-reaction is as follows:
The reaction takes place in acidic medium. Balance oxygen by
Now, add electrons to balance charge. To balance charge on both side, add four electrons to the left. Hence, the balanced equation is-
(b)
Interpretation: The given half-reaction which take place in acidic solution needs to be balanced.
Concept Introduction: By transfer of electrons, oxidation-reduction reactions are characterized. The transfer occurs to form ions. Oxidation reaction is caused by losing electrons and reduction caused by gaining electrons.
(b)
Answer to Problem 25A
Balanced half-reaction is-
Explanation of Solution
The given half-reaction is as follows:
First balance Iodine by multiplying reactant side
The reaction takes place in acidic medium. Balance oxygen by adding
Now, add electrons to balance charge. To balance charge on both sides, add 12 electrons to the left. Hence, the balanced equation is-
(c)
