Acids and bases

  1. Feb 11, 2009 #1
    I did an experiment with

    a) strong acid (HCl) and strong base (NaOH)

    b) weak acid (ethanoic) and strong base (NaOH)

    so, im looking at the heat of energy for both the reactions, and so i found that reaction a had a greater heat of energy was that of the reaction b) weak acid and strong base, (using the formula deltaH= mcT)

    why would this be, in terms of dissociation or bond strenghths? i know that acids completely dissociate, but not too sure about the difference between weak acid and strong acid.... help please!!

    Show your numbers.

    Weak acids are not completely dissociated.

    Are you neutralizing here? What are the values that you got?
