Homework Help: Graphing the 1st Derivative on excel?

  1. Oct 3, 2007 #1
    I have a titration curve (pH vs NaOH added) and i want to determine the endpoint of this graph
    i want to use excel to make a graph of it's derivative (dy/dx) but i don't know how?

    does anyone know how?
    is there an option i can choose when making the graph?

    You can calculate dy/dx (actually delta pH/delta volume) and graph the result. Pretty straightforward that way.
