    Hi guys,

    I have a titration lab this friday... er.... tomorrow. I was wondering if any of you had any advice. One question I have is: "How do I know when I have reached endpoint?"

    The indicator is phenolphthalein. Should the color of the solution still be clear or a ligh tint of pink?

    depends on the titration it is?

    it goes pink in the ph range of 8-10

    what exactly are you titrating? i have only ever worked with this indicatior in above conditions?

    Should be colourless, most probably.
    Doubt it'll be a slight tint of pink cause its hard to judge how slight the slight pink is.
    And colourless, if it goes acidic than too bad.
    Pretty ambiguous actually
    Using methyl orange would be much better i guess.
