What is true about the amount of H+ (acid) and OH- (base) in a solution at the equivalence point of a titration? How can we know that the endpoint in a titration has been reached?

Question

At the equivalence point both concentrations are equal, you can normaly observe a change in the color of the soln after this point is reached because of a chemical you add to the soln called Phenolphthalein.

If we observe a color change, does that mean that the endpoint in a titration has been reached as well?

anonymous · Answer

all that means is that you changed the soln from eith acidic to basic or basic to acidic. The chemical is really just a visual indicator letting you know that you have made the [oh-] greater than the [h+]. But i would say that you reached the endpoint, when you see the color change.
