Numbers to Balance Equations
|Some equations can be balanced by sight. Others require
on the part of the student. Some equations cannot be balanced by sight
and ones involving many reactants and products can be almost impossible
to solve. Below is a method of balancing using redox numbers that works
all reaction no matter how complex.
|Step 1 Write the correct formulas for all the reactants
|Step 2 Assign oxidation numbers to the atoms in the
|Step 3 Identify which atoms change their oxidation numbers.
|Step 4 Make the number of atoms that change oxidation
same on both sides by inserting temporary coefficients.
|Step 5 Compute the total change in oxidation
number for the
oxidation and reduction that occur.
|Step 6 Make the total increase in oxidation number equal
decrease by multiplication using appropriate factors.
|Step 7 Balance the remainder by inspection.
