What else can I help you with?
Is the indicator generally added to the titrant or the analyte in a titration?
Analyte is the indicator that is generally added in titration.
What is the color of the indicator when an excess of hydrochloric acid has been added?
The indicator turns pink when an excess of hydrochloric acid has been added in a titration.
Why are only a few drops of indicator used in a titration?
Only a few drops of indicator are used in a titration to avoid affecting the results by introducing excessive impurities into the solution. The indicator is added to help visually determine the endpoint of the titration, where the reaction is completed. Adding more indicator than necessary can lead to errors in the measurements.
What changes color at the endpoint of titration?
The color change at the endpoint of titration is usually due to an indicator that has been added to the solution being titrated. The change in color indicates that the reaction is complete and can help determine the endpoint of the titration.
Why is nitrobenzene added to titration mixture?
Nitrobenzene is added to the titration mixture as a color indicator for the endpoint of the titration. It imparts a pink color to the solution which disappears when the reaction is complete. This helps to visually determine when the equivalent point has been reached.

The indicator turns pink when an excess of hydrochloric acid has been added in a titration.
When are drops of indicator most likely added to the Erlenmeyer flask?
Drops of indicator are most likely added to the Erlenmeyer flask just before the titration begins, after the titrant has been prepared and the analyte solution is in the flask. This ensures that the indicator can effectively signal the endpoint of the titration process by changing color in response to the pH change as the titrant is added. Adding the indicator too early may lead to degradation or interference before the actual titration occurs.

Why starch is added towards the end of titration?
Starch is added towards the end of titration as an indicator to help visualize the endpoint. When the starch is added, the solution will turn blue-black in the presence of excess iodine, indicating that the reaction is complete. This color change helps in accurately determining the endpoint of the titration.
Why you add starch at the end of titration?
Starch is added at the end of titration as an indicator to signal the endpoint of the reaction. It forms a complex with the iodine produced during the titration, resulting in a color change from clear to blue-black, indicating that the titration is complete.
Why is indicator added to a pipette solution before titration?
I'm not sure what you really mean. There wouldn't be any point adding it afterwards! It's there to reveal the end point of your titration. You could add it when you thought you were near the end point, but it's easier to put it in before you start.
Why starch indicator is not added right from the beginning of titration in iodometry?
Starch indicator should not be added at the beginning of an iodometry titration because iodine can form a complex with the starch, resulting in a blue-black color that can obscure the endpoint. It is best to add the starch indicator near the endpoint, when the iodine is almost completely reacted, to help visualize the color change.
