In permanganometric titration what is the the self indicator and how does it work?
In permanganometric titration, the self-indicator is the permanganate ion itself. It works by changing color during the titration process from purple to colorless when the endpoint is reached. This color change indicates the completion of the reaction between permanganate ion and the analyte.
How long last the end point of permanganometric titration?
The end point of a permanganometric titration typically lasts for several seconds to a couple of minutes. It depends on factors such as the concentration of the analyte and the reaction kinetics. It is important to record the exact volume of titrant added when the color change occurs to ensure accurate measurement.
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 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.
What is the pH at the second equivalence point in a titration?
The pH at the second equivalence point in a titration is typically around 9 to 10.

Why Potassium permanganate act as self indicator?
as it is pink in colour so no external agent is required for titration when we titrate againist another component it will changes it colour to pale pink asd it is end point

What is meant by neutralization point in the neutralization titration?
The neutralization point in a neutralization titration is the point at which the acid and base have reacted completely to form water and a salt, resulting in a neutral solution. This point is often indicated by a sharp change in pH, signaling the endpoint of the titration.
How do you determine the end point from titration in acid base titration process?
it depends on the indicator used, i.e. phenolphthalein is the most popular. this is colourless in acid, purple in base, very identifiable. Keep actively swirling and when it is expected to turn (figured from a rough titration beforehand) add very slowly dropwise untill the colour turns.
The purpose of an indicator in a titration experiment?
The indicator is used to measure the end point of titration. Methyl red and phenolphthalein are frequently used indicators in acid-base titration. Potassium permanganate can used as a self indicator in redox titrations where applicable.
What is the endpoint of a titration?
The endpoint of a titration is the point at which the reaction between the titrant and analyte is complete. This is typically determined by a change in a physical property, such as a color change or a sudden change in pH, indicating that the equivalence point has been reached.
What is the stoichiometric point of a titration called?
The stoichiometric point of a titration is called the equivalence point. At this point, the moles of acid and base have reacted in exact stoichiometric proportions, resulting in complete neutralization.
The point in a titration at which the indicator changes is called the?
End point...
