F336 Chemistry A2

Hi, i'm investigating Acid-base titrtations and how changing concentration affects the pH Curve.

I'm slightly confused about what the 'End-Point' is for the titration.
Am i supposed to end the titration as soon the indicator changes the colour?
My goal is to get a pH curve which normally forms an 'S' shape.

I'm thinking that if i stop at when the indicator changes colour then i would only have half of the graph. im not too sure about this, can some one please help me out :s

Hi, my investigation is Acid-base Titrations.

I just need clear understanding about when to 'End' my titration.
my goal is to achieve a full pH graph with a shape of an 'S'.
Am i supposed to stop when indicator changes colour?
I'm thinking that if i end it when it the indicator changes then i'm going to have a graph that end at the equivalance point or half of a graph :s-smilie::confused:
