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.
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.
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.
Is methylorange the indicator used in the titration of Na2CO3 against HCl solution?
Methyl orange is not commonly used as an indicator in the titration of Na2CO3 against HCl solution. Phenolphthalein is a suitable indicator for this titration because it changes color in the pH range of the equivalence point.

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.
What is the role of an indicator in the titration process?
An indicator in the titration process is a substance that changes color at or near the equivalence point of the reaction. It helps in determining the end point of the titration by signaling when the reaction between the analyte and titrant is complete. The choice of indicator depends on the type of titration being performed and the pH range of the reaction.
What color will a solution be at the equivalence point of titration?
The color of a solution at the equivalence point of a titration depends on the type of indicator used. The indicator changes color at a specific pH value, signaling the completion of the reaction. Common indicators like phenolphthalein turn pink at the equivalence point of an acid-base titration.
In a titration when does the indicator change color?
when the equivalence point of a titration is achieved.. Added: (More precisely:) The equivalence point is the point where the number of moles of base equal the number of moles of acid. The end point is the point where the indicator being used changes color (also 'indication point)'. If the indicator is chosen correctly, the end point will essentially be exactly as near as possible at the equivalence point. The point of the titration is to find the equivalence point -- the end point is just a very close approximation to it. This is because the pH of the solution changes very rapidly close to the equivalence point. Therefore, the indicator will change color very close to the equivalence point because of the steepness of the pH change
What is another example of indicator that used in titration with EDTA?
Another example of an indicator used in a titration with EDTA is Eriochrome Black T. This indicator changes color from red to blue when it forms a complex with metal ions, allowing for the detection of the end point in the titration.
Describe a method to visually detect the end point of a titration without the use of instruments?
The method used most often in chemistry labs is by use of a pH indicator in the sample being titrated. When you reach the titration point, the indicator will change colors, demonstrating the end point of the titration.
What is Fajan's method of argentometric titration?
Fajan's method of argentometric titration involves the use of potassium chromate as an indicator to detect the end point of a titration between silver ions and chloride ions. The indicator changes color from yellow to red when all the chloride ions have reacted with the silver ions, marking the end point of the titration.
