yes,its true that colour changes at the endpoint of titration but in some cases coloured solution become colourless.it indicate end of a reaction in which one substance has been fully used up.indicators are used to locate the endpoint but in certain cases reactant or product itself is coloured which at endpoint become colourless or coloured.

The color change at the endpoint of a titration is due to the indicator used. Indicators are substances that change color at specific pH levels, signaling the completion of the reaction. The choice of indicator depends on the pH range over which the titration is performed.

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.
What is the name for the point at which the indicator changes color in a titration?
The point at which the indicator changes color in a titration is called the "endpoint". It signifies the completion of the reaction between the titrant and analyte in the solution being titrated.
Why was the conical flask placed on a white piece of paper in titration?
The white paper helps to provide a clear background for observing color changes during the titration process. This is important for accurately determining the endpoint of the titration when the color changes indicate the completion of the reaction.
What colour changes you see in edta titration?
In EDTA titration, the color changes typically involve a transition metal complex forming with EDTA. For example, in the titration of calcium ions, a color change from red to blue indicates the formation of a complex between EDTA and calcium ions. This color change signals the endpoint of the titration.
Why do you put a white paper under the titration flask?
A white background makes it easier to see color changes in the solution during titration, improving the accuracy of the endpoint determination. It enhances the visibility of subtle color changes, ensuring the titration results are more precise and reliable.

Changes color at the endpoint of titration?
The color change at the endpoint of a titration is due to the indicator used in the titration process. The indicator changes color based on the pH of the solution, signaling the completion of the reaction between the analyte and titrant. This color change helps determine the equivalence point of the titration.

The point at which a drop of base changes the color of an acid solution and the color persists?
This point is known as the endpoint in a titration. It signifies that the reaction between the acid and base is complete. The color change usually happens due to the addition of an indicator, which changes color at a specific pH.
What is endpoint in titration?
In titration, an endpoint is the point at which the reaction between the analyte and titrant is complete. It is often indicated by a significant change in color or another physical property of the solution, signaling that the equivalence point has been reached. The endpoint helps determine the concentration of the analyte in the sample being analyzed.
How does the equivalence point differ from the endpoint of a titration?
The equivalence point in a titration is the point at which the moles of titrant added are stoichiometrically equivalent to the moles of analyte present. The endpoint is when an indicator used in the titration changes color, signaling the completion of the reaction. The equivalence point is a calculated value based on the stoichiometry of the reaction, while the endpoint is detected visually.
What is double indicator titration?
Double indicator titration is a type of titration method that involves the use of two different indicators to determine the endpoint of the reaction. The first indicator changes color near the starting pH of the titration, while the second indicator undergoes a distinct color change at or near the endpoint of the titration. This technique is commonly used in complexometric titrations to determine the concentrations of metal ions in a solution.
What is the term for the stage in an acid-base titration when the indicator changes color?
The term for the stage in an acid-base titration when the indicator changes color is called the endpoint. It signifies that the stoichiometric equivalence point has been reached, where the acid and base have reacted completely.
What is the difference between end point titration and equivalence point?
Endpoint titration refers to the point in a titration where the indicator changes color, signaling that the reaction is complete. Equivalence point, on the other hand, is the point in the titration where the moles of the titrant are stoichiometrically equal to the moles of the analyte. The equivalence point does not necessarily coincide with the endpoint, as the indicator may change color before or after reaching the equivalence point.
