Acidic/ basic conditions

Postby AlyssaPeckham1A » Sat Mar 17, 2018 11:07 pm

Other than using H+ or OH-, is there a main difference in balancing acidic vs basic reactions?

yeah I think the only difference is adding OH- to balance the H+. Then the OH- and H+ ions on the same side can be added to form H2O

For basic equations, they say balance the O's by adding H2O to the side that needs it, then add to the other side the an H2O for every H atom present. And add to the same side an OH for every H present.

See page 567 for more details.

That is essentially the only difference with regards to balancing the half reactions.

Balancing a basic solution just takes a bit longer and is a bit more complex since there are more steps. First you balance the oxygens by adding H2O, then you balance the hydrogens by adding H+ (this is where you would stop if it were an acidic solution), then you balance the H+ by adding OH-, then you combine the H+ and OH- to make more H2O, and finally you cancel out/add up all the H2Os.
