In acid-base titration one of the following is incorrect: O The equivalence point will be sharp when the both acid and base are strong. O The end point will be sharper when more concentrated solutions are used. A suitable indicator should have pH of color transition of pH = pKa±1. Incomplete reactions show sharper end point. If the equivalence point doesn't match with the end point the titration error will be high.
