Indicator End-point
What is Indicator End-point?
The point in a titration at which the indicator shows a permanent change of colour, indicating that the reaction between the two solutions in the flask is just complete. It is reached by adding the solution from the burette drop by drop while swirling, and is taken at the first colour change that does not disappear on swirling. The colour seen depends on which indicator is used and which solution is in the flask.
This definition is part of the Experimental Techniques and Chemical Analysis chapter in Cambridge O Level Chemistry.
