OH and H

Postby Wilson 2E » Sun Mar 01, 2020 6:45 pm

When balancing reactions in basic and acidic solution, will OH and H, respectively, be a product or reactant, or can it be either? If either, is there a pattern?

For OH and H, you would add them on whichever side is needed so that all the elements are balanced on both sides of the equation.

OH- and H+ can be both reactants and products in your redox reaction. This varies case to case, so you would have to balance each of your half reactions and see what needs to be balanced in order to determine where the OH- or H+ is needed.

OH- and H+ can be added on either side. Remember OH- is for basic solutions and H+ is for acidic solutions.

They can be on either side cuz you just add them to make sure that everything is balanced

They can be on either side, the equation just needs to be balanced

I think for this case - balancing redox reactions - I think it's either or since the primary goal is the balance them and their respective elements/charges.

As long as the equation is balanced, they can be on either side of the equation.

In a test style problem, would the question say something alongs the lines of "In the acidic rxn..." or must we be able to identify that? Otherwise, if we were to accidentally use OH- when we were supposed to use H+, would a significant number of points be taken off?
