    There's really not much you need to know about PH curves.

    The equilvalence point is the point when the graph is nearly vertical due to the addition of one drop of alkali.

    You need to know the general trends of curves:
    e.g. strong acid with strong base
    strong acid/weak base and vice versa
    weak acid and weak base

    and then the typical exam question is:
    Q. What type of indicator would you use with the following reaction ?

    if you memorise around 3 indicators (one for each reaction)...then that's all you need.

    I think that should should help ?.....if it's more specific then just post back.
