Answer 1

When you balance a redox equation using the half-reaction method, what do you do after you balance the atoms and charges?

Answer 2

Determine the oxidation numbers for the elements.



Write the oxidation numbers for the elements.



Add back in any spectator ions.



Add the two half-reactions to show the overall redox equation.



Use a coefficient to make the number of electrons lost equal the number of electrons gained

Answer 3

Answer 4

Here is my rules for balancing redox

Rules for balancing Redox equations:

1) Determine the oxidation state (charge) of each atom of each element.

2) Determine which element’s atoms have changed oxidation number from the left side of the equation to the right side of the equation.

3) Write the equation as 2 half-reactions. Include the particles (atoms, ions, molecules) which are involved in change of oxidation state.

4) Balance all atoms and ions, except O and H, with the use of coefficients.

5) To balance the O’s, add enough water (H2O) to the side deficient in O atoms.

6) To balance the H atom, add enough H+ to the side deficient in H atoms.

7) Balance the charge by adding electrons to the side deficient in negative charges.

8) Multiply the half-reactions by smallest whole numbers to balance electrons.

9) Add the 2 half-reactions and subtract any duplications.

If the reaction occurs in a basic solution, add the same number of OH-1ions to both sides to equalize the number of H+1 ions.

Answer 5

Use a coefficient to make the number of electrons lost equal the number of electrons gained.

then

Add the two half-reactions to show the overall redox equation
