Question

MEDALSSSSS!!!!!!!!!!!!!!!!!!!!!!

When balancing the oxidation and reduction half-reactions for basic 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

Answer 1

@Nnesha can you help me out?

Answer 2

@Compassionate do you know if it is A or C?

Answer 3

I know that this question is regarding basic solutions. However, it may be helpful to first think of acidic solutions. Do you know how to balance a redox reaction in acidic solution?

Answer 4

use H+ and OH− equally in order to balance the equation
use OH− and H2O, as needed to balance the equation

I use H+ then neutralize them with OH- to form H2O and add the same number of OH- in the other side of the reaction
