What is the purpose of adding dextrin in titration?
In a precipitate titration, dextrin is added to prevent the precipitate from coagulating during titration. It also makes the color change more visible, since some analytes may be difficult to see a color change during the titration. I hope this helps! This is straight out of my Analytical Lab manual.
What is colourimetric titration?
Titration in which the end point is marked by a color change.
What happens during an acidic base titration in the presents of an indication?
The indicator will change color as the pH changes.
What is the function of an indicator in titration?
Change color
What is a potentiometric titration?
A potentiometric titration is one in which the end-point is detected by measuring the change in potential of a suitable electrode during the titration.

What changes color at the endpoint of titration?
change in pH, changes the colour (of the indicator)
What does a color change in an acid-base titration mean?
according to change of PH of medium where the indicator color is changed according to PH of medium
Why is the vinegar diluted before titration?
1. The advantage in diluting the solution before titration is that it allows for greater accuracy in the titration; this is because the color change in the solution is easier to observe if it is a dilute solution.
Why is important that the indicator is present in the solution during the course of titration?
the reason why a indicator is important in some titration is to show a change in the solution. for example as a solution runs from acidic to basic the indicator may turn a different color. but this is the reason why it is important inmost experiments.
What is the color of the end point for the titration of the acid?
A general acid-base titration may not indicate a color change. Therefore an indicator is used. Among the most used indicators are methyl red, methyl orange and bromothymol blue.
Is titration a chemical change?
Titration is a chemical process.
What is a function of an indicator in a titration?
The function is to change color. This happens when all the H+ ( or H3O+) from the acid has been neutralized, an indicator in the sample will change
