In a titration the pipette is used to transfer 25 cm3 (usually to ±0.05 cm3) of a solution into a conical flask. Another solution that reacts with the solution in the conical flask is carefully added from a burette until it has all exactly reacted. This is called the end point of the titration (or equivalence point of the reaction). There needs to be a way of knowing when the end point is reached. An indicator may be needed. Often a titration is repeated until successive titres are within 0.1 cm3.

Describe a method to visually detect the end point of a titration without the use of instruments?
The method used most often in chemistry labs is by use of a pH indicator in the sample being titrated. When you reach the titration point, the indicator will change colors, demonstrating the end point of the titration.

Why is phenolphthalein an appropiate indicator for back titration?
it's not in all cases. Only for titration of weak acids.
What is the purpose for using phenolphthalein for an acid base titration?
It's the colour indicator you watch for during the titration.
