Neutralization Reaction

  1. May 11, 2007 #1
    Is it correct to talk about a "Neutralization Reaction" when we make a titration of a weak acid with a strong base, or it is only correct if we titrate a strong acid with a strong base or a strong base with a strong acid? Thanks.:smile:

    neutralisation involves rxn between H+ and OH-
    whenever there is a rxn between an acid and a base, it is always a neutralisation one!!!

    moreover, a weak acid will ionise completely during neutralisation.

    as the OH- reacts with the H+ from the weak acid, the latter H+ decreases in concentration. According to Le Chatelier's principle, the weak acid will dissociate to produce even more H+!!! eventually, the weak acid will end up dissociating completely!!!

    But final solution, at 25 ÂșC, has not pH=7! i.e. is not a neutral solution!

    Technically, a neutralization reaction produces a pH 7 solution of salt. This may require more titrant than an equinormal amount if weak acids -strong bases or strong acid - weak bases are used. So, in the broadest sense, a neutralization reaction is not always a titration unless strong acids and strong bases are being used.
