Interpretation:
The reason for adding water and hydronium or hydroxide ion for balancing an equation is to be determined.
Concept introduction:
A balanced equation contains equal number of atoms on both the sides of the equation. It is very important to balance an equation. There are different ways to balance a chemical equation depending on the acidic or basic medium. This is done in accordance with the law of conservation of mass.
The reaction generally takes place in an aqueous solution. So, water can be added to it to balance the chemical equation.
If the reaction occurs in acidic medium. Hydronium ion
If the reaction occurs in basic medium. Hydroxide ion
