Workshop 5: Titration Curves A pH or titration curve can be produced by plotting the pH of a solution (containing an analyte) versus the volume of added The equivalence or end point of a titration occurs when enough titrant has been added to consume all the acid or base initially present in the analyte.You know you have reached the endpoint when you see a significant change in the pH of the solution. Part Lets begin by analyzing a titration curve...
