When balancing redox equations, once you get to the half reactions, if you want the equations to be acid or base, do you use the same method of adding H2O and H+ in order to balance the equations?

If you have an acid/base reaction, one of your half reactions will probably be a simple, one element to one element +electron reaction, while another will involve compounds. For the more complicated compound, just write the half reaction with H+ and H20 added to it looking at the main reaction.

Are you asking if the method for balancing redox half reactions is the same in acidic and basic solution?
If so, I'd be happy to reply again and give an explanation :-)

Why do you have to take the square root of K, and when do you take it?

When you using the equation: E(cell) = E(cathode) - E(anode) how do you determine which is the anode and which is the cathode?
