Chapter 15, Problem 51UTC
(a)
Interpretation Introduction
Interpretation:
The following half reaction in acidic medium should be balanced.
Concept Introduction :
A half reaction for a redox
In oxidation, loss of electrons occurs whereas in reduction, gain of electrons occurs.
A balanced reaction is a reaction in which number of atoms and charges should be equal on both reactant as well as on product side.
(b)
Interpretation Introduction
Interpretation:
The following half reaction in acidic medium should be balanced.
Concept Introduction :
A half reaction for a redox chemical reaction shows the half component of a given redox reaction which means it will show the oxidation and reduction of half reactions separately.
In oxidation, loss of electrons occurs whereas in reduction, gain of electrons occurs.
A balanced reaction is a reaction in which number of atoms and charges should be equal on both reactant as well as on product side.
