Net Ionic Equation. A chemical reaction involves the conversion of reactant atoms or molecules to product. During any chemical reaction, reactant molecules are joined together to form a product which has different chemical and physical properties than the reactants.
This is called the Total Ionic Equation. 3) Then, you simplify by canceling things out if they appear on both sides of the reaction, resulting in the Net Ionic Equation. or write one reduction half and other oxidation half and simply add them
