    i will like to know how to do a titration curve when entering values like the molarity and volume of an acid/base, the graph changes.

    The x-axis should have pH value and -axis should have the volume added.

    Thanks...

    At last I find you!

    You emailed me, though you had your membership here so as to not allow people to email you, and your other email address didn't work!

    So, what's your problem? Here's the email reply I wrote to you that got sent back....

    Mr CosmicPower

    Did you just wake up this morning wanting to do this, or do you have more to go on?

    What are you plotting against what? pH versus volume? pH versus time? And to save me going to look it up - what relationship exists between the variables you are plotting against each other? If you are wanting to do a statistical analysis of H and OH ions, then you'll need a model of molecular interaction.

    What have you got so far!

    Thanks for the reply.
    Sorry for causing so much trouble for you.

    Actually,I want to create an interactive titration curve.
    User will be given choices of different combinations of strong and weak acid and base.

    When he has selected the combination of acid and base, the
    screen will prompt him/her to enter the molarity and volume of acid/base needed.

    After pressing the "Draw" button, the titration curve will be simulated.

    The titration curve should illustrate the equilvalent point
    with comments on the appropriate indicator.

    You can try this site...it is quite similiar to the one i was refering to.

    OK what have you got so far? And whats the relationship between molarity and pH?
