Balance elements in the equation other than O and H.

Balance the oxygen atoms by adding the appropriate number of water (H₂O) molecules to the opposite side of the equation.

Balance the hydrogen atoms (including those added in step 2 to balance the oxygen atom) by adding H⁺ ions to the opposite side of the equation.  

Add up the charges on each side. Make them equal by adding enough electrons (e^-) to the more positive side. (Rule of thumb: e^- and H⁺ are almost always on the same side.)

The e^- on each side must be made equal; if they are not equal, they must be multiplied by appropriate integers (the lowest common multiple) to be made the same.

The half-equations are added together, canceling out the electrons to form one balanced equation. Common terms should also be canceled out.

• (If the equation is being balanced in a basic solution, through the addition of one more step, the appropriate number of OH^- must be added to turn the remaining H⁺ into water molecules.)
• The equation can now be checked to make sure that it is balanced
