Chapter 20, Problem 21QAP
Interpretation Introduction
Interpretation:
The
Concept introduction:
The redox equation can be balanced by following a few steps:
Step1: Split the reaction into two halves; oxidation and reduction half.
Step2: The half reaction should be balanced.
Step3: Number of electrons should be made equal in both the reaction halves by multiplying with suitable coefficients.
Step4: The half reactions should be added and electrons should be cancelled to get final reaction.
Step5: General reactions can be balanced by balancing the number of atoms of each element in the molecules of both the LHS and RHS sides.
