When balancing the oxidation and reduction half-reactions for acidic solutions, you should:

use H+ and OH− equally in order to balance the equation

use H+ only in order to balance the equation

use H+ and H2O, as needed to balance the equation

use OH− and H2O, as needed to balance the equation

You: So I know I need H+ cause it's in acid.
Me: Right!
You: Since it's in acid we won't be balancing with OH
Me: Yeah good job
You: And i'll probably need H20 to balance the H+'s
Me: Yeah that's right too!
You: So It's probably C(the third one down.)
Me: Wow you're really good at this.
You: Yeah, I know. You deserve a good answer!
Me: Thanks!
