Concept introduction: In
To determine: The balanced form of given redox reaction in acidic solution.
Answer to Problem 18.1P
Solution:
The balanced form of given redox reaction in acidic solution is,
Explanation of Solution
The redox reaction in acidic solution is,
The above redox reaction is unbalanced.
In balanced form of redox reaction number of atoms and total charge of reactants and products are same.
To balance the above equation (1) following steps are followed.
Step 1:
Calculate the oxidation state of each atom.
The oxidation state of
The oxidation state of
The oxidation state of
The oxidation state of
Step 2:
Identify the oxidation and reduction reaction and separate them as half reactions.
In oxidation process, positive oxidation state of atoms increased by some number.
In reduction process, positive oxidation state of atoms decreased by some number.
Step 3:
Balance the atoms of reactant and product.
To balance
Step 4:
Balance each half reaction with respect to charge.
Balance the charge of oxidation half reaction by the addition of
Balance the charge of reduction half reaction by the addition of
Step 6:
To get overall reaction add the half reactions together and remove common terms.
Thus, the balanced form of given redox reaction in acidic solution is,
The balanced form of given redox reaction in acidic solution is,
