### Balancing Redox Reaction with Hydrogens

Why do some redox reactions involve hydrogen protons as well? For example, in problem 14.1.b and 14.1.c, the half reactions are balanced with both hydrogen protons and electrons.

When balancing redox reactions, you always use $H_{2}O$ to balance out the oxygens. In acidic conditions, you would then use H+ to balance the hydrogens in the reaction.

### Re: Balancing Redox Reaction with Hydrogens

My TA gave us a list of steps for how to balance redox reactions!

Step 1: Write the skeletons of the half-reactions
Step 2: Balance all elements other than H and O
Step 3: Balance O by adding H2O to the side without O
Step 4: Balance H by adding H+ to the side without H
Step 5: Balance charges by adding e- (electrons)
Step 6: Balance overall charges of both half-reactions by multiplying by a common factor
Step 7: Add the two reactions
-If acidic, stop here
-If basic, continue to step 8
Step 8: Add OH- to both sides to cancel H+ ions
Step 9: Combine OH- and H+ to form H2O
Step 10: Cancel H2O molecules and check charge balance

Hope this helps!
