1.	Highlight three ways in which end point can be achieved without an indicator
Answer» tion:The indicator used for the detection of end point in WEAK acid and strong base TITRATION is phenolphthalein.A potentiometer or a redox indicator is usually used to determine the endpoint of the titration, as when one of the CONSTITUENTS is the OXIDIZING agent potassium dichromate. The color change of the SOLUTION from orange to green is not definite, therefore an indicator such as sodium diphenylamine is used.
