How to Balance Half-Redox Equation in Acidic Condition



This video is the most important for grade11 or grade12 to improve about redox equation in acid.

To balance chemical equation:

1- balance the atom different from oxygen or hydrogen firstly

2- balance the oxygen atom if lack of oxygen atom; must add water molecule
“ if lack of one oxygen atom, have to add one water molecule”
“ if lack of two oxygen atom, have to add two water molecule”
“ if lack of three oxygen atom, have to add three water molecule”

3- balance the hydrogen atom if lack of hydrogen atom, must add ionic hydrogen or ionic hydronium.

4- balance electrons; it is added to the left or right that is excess.

welcome your question.
