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...

To learn about titration types
and how to calculate pH at different points of titration. In an
acid-base titration, a titrant (solution of a base or acid) is
added slowly to an analyte (solution of an acid or base). The
titration is often monitored using a pH meter. A plot of pH as a
function of the volume of titrant added is called a pH titration
curve. Prior to the titration, the pH is determined by the
concentration of the...
