Q&A (Chemistry)
@ 9:08 PM
Q:Whats the difference between equivalence point and end-point of a titration?
A:The equivalence point is the point where the number of moles of base equal the number of moles of acid. The end point is the point where the indicator being used changes color (also 'indication point)'.
If the indicator is chosen correctly, the end point will essentially be exactly as near as possible at the equivalence point.
The point of the titration is to find the equivalence point -- the end point is just a very close approximation to it. (Src: wiki.answers.com)
