How To Determine What Indicator To Use In A Titration

how to determine what indicator to use in a titration

Which indicator is best in silver nitrate titrations

In this experiment you will use the indicator phenolphthalein, which undergoes a sudden change in colour from pink in basic solution to colourless in acidic solution. The midpoint of the colour change occurs at a pH of 9.5, i.e. already slightly basic. This is a perfect choice as an indicator for the titration of acetic acid with hydroxide ion, because the solution at the equivalence point of

be using an indicator called phenolphthalein for this experiment. In a basic solution (a solution that contains more base than acid), phenolphthalein is pink. In solutions that are acidic (a solution that contains more acid than base), phenolphthalein is colorless. During the titration performed in this experiment, the point where the indicator first changes from colorless to pink corresponds

Which indicator is best in silver nitrate titrations

26/11/2009 · instead of using an indicator, how else could the end point for a titration reaction be found? And of course the pH of the solution can be followed to determine the equivalence point of the titration. All of these methods involve going past the endpoint of a titration, and the equivalence point is determined after the fact, so to speak, rather than stopping at a signal produced by a color

Students can be encouraged to carry out the titration initially without the indicator as they can then see for themselves how difficult it is to determine the endpoint. They would then see the purpose of using an indicator. The potassium chromate indicator will not be effective under acidic or alkaline conditions.
