Question

Why adsorption indicator shows color change only at end point?

Answer 1

Answer:

solutions the end points are sharp. Coagulation of the precipitate starts much before the end point. The coagulated precipitate also attains pinkish tinge, but at the end point its colour changes to deep pink and coagulation is complete. With 0.02 N solutions the change of colour occurs slightly after the end point.
