Balancing Equations - Acidic and Basic Solutions

When we take in account reactions that are acidic or basic, we must consider the hydrogen ion and hydroxide ion. The overall approach regarding balancing these equation is very similar to a simple reaction, however, few more steps are required.

1. Write the unbalanced equation that show the formulas of the given reactants and products.
2. Balance the atoms other than oxygen and hydrogen.
3. Balance the atoms of Oxygen by adding water.
4. Balance the hydrogen atoms by adding hydrogen ions. (At this point, if we are dealing with an acidic solution, balance the charges by adding the electrons.)
5. If we are dealing with a basic solution: Add to both sides, the same number of hydroxide ions as the number or hydrogen ions present.
6. Add the hydrogen and hydroxide ions on the same side to form water.
7. Cancel and water molecule present on both sides of the reaction.
8. Balance the charges by adding the electrons.
