WebAug 31, 2024 · An endpoint represents the stage of titration that indicates the completion of the titration with the help of the change in colour or intensity of the solution. What is an endpoint on the pH scale? If a few drops of indicator solution have been added, this sharp increase in pH causes an abrupt change in color, which is called the endpoint of ... WebA titration curve is a plot of some solution property versus the amount of added titrant. For acid-base titrations, solution pH is a useful property to monitor because it varies predictably with the solution composition and, therefore, may be used to monitor the titration’s progress and detect its end point.
