QUESTION 1 Put the following steps in order for solving a redox reaction in acidic solution by the half- reaction method. If the H+ ion exists in either the products or the reactants, add the same number of H20 to BOTH sides of the equation as the number of H+ ions, thereby making hydronium on one side of the reaction. Write the oxidation and reduction half reactions (separately). Cancel any common items on the reactant and product side Determine what has been oxidized and what has been reduced Add the half reactions. Bala nce the half reactions for charge, adding electrons to the more positive side of the half reactions, Multiply each half reaction by a number if necessary. Balance the half reactions for mass, adding water when appropriate to balance oxygens, and adding H+ to balance hydrogens.

Explanation / Answer

1.Determine what has been oxidized and what has been reduced.

2.Write the oxidation and reduction half reactions separately.

3.Balance the half reactions for mass, adding water when appropriate to balance oxygen and adding hydronium ions to balance hydrogen atoms.

4.Balance the half reactions for charge, by adding electrons to the more positive side of the half reactions.

5.Multiply each of the half reactions by a number such that the number of electrons gets cancelled when both the half reactions are added.

6.Add the both oxidation and reduction half reactions.

7.If the hydronium ions exists either on product or reactant sides, then add the same number of water molecules to both sides of the equation as the number of H+ ions,there by making hydronium on one side of the reaction.

8.Now cancel all the common items on reactant and product sides(if any) .
