    I'm a bit confused with acidic buffer and what happens when you add OH-.

    I sort of get why the equilibrium shifts to the right (to oppose the change).
    But what actually happens.
    I've read something about it reacting with H+ to form water - That reduces the concentration of OH-
    But does anything happen with the ethanoic acid?
    I'm not too sure tbh.

    I'm using the example ethanoic acid and sodium ethanoate.

    Cheers

    EDIT: Is the OH- reacting with H+ to form water. H+ is being used up so the equilibrium shifts to the right to maintain the concentration of H+.

    Look, here's an interactive on buffers that I prepared, which should answer all of your questions. Go through it slowly and then come back with specifics.
