OH or H20

When do we use OH versus H2O to balance the hydrogens on both sides. Are they interchangeable?

when balancing half reactions, h20 will generally be used to balance oxygen, but when in a basic environment, OH should then be used to balance the excess hydrogen

When balancing half reactions first balance the Oxygens with H2O then depending on the type of solution it is you either add H+ to balance the hydrogens from H20 (in an acidic solution, usually the question will explicitly state it) or OH to balance the H from H20 (basic solution).
