Interpretation: The balanced redox equation for the reaction between
Concept Introduction: A Redox reaction leads to oxidation and reduction processes simultaneously.
Answer to Problem 6RQ
Explanation of Solution
Given information:
Assign oxidation number to each atom:
Oxidation half-reaction must include oxidation step in which elements show increase in oxidation state. Here the oxidation state of Ag decreases from +1 to 0. Thus, the reduction half-reaction can be written as;
Oxidation half-reaction must include oxidation step in which elements show increase in oxidation state. Here the oxidation state of Cu increases from 0 to +2. Thus, the oxidation half-reaction can be written as;
Balance charges:
Step-5:
Add both equation:
Thus, the balance equation is:
