Basic v Acidic

Postby Mary Becerra 2D » Sat Feb 17, 2018 10:47 pm

How do we know when to balance the equation using basic or acidic methods? Is it possible to use both when balancing the same equation?

I'm not sure if this helps but my TA said to just assume acidic conditions unless otherwise stated, and if it is a basic solution, solve it as if it were acidic and then convert to basic at the end.

To balance in basic solution, first balance the half reactions as if they were in acidic solution and add them together. Then, add OH- ions to both sides in the same number which H+ions are present on one side. (i.e. if you have 6H+ ions, then add 6OH- ions to both sides) The side that has 6H+ and 6OH- will combine to form 6H2O. Lastly, camel out the new water molecules formed with the water molecules that were already present.
