WebThe titration curve is a graphical representation that depicts the correlation between the pH of a solution, typically an acid, and its corresponding volume. The indicator is employed to ascertain the endpoint of a titration, which is the point at which the quantity of base added is sufficient to neutralize all of the acid present in the solution.
