Why potassium permanganate is used as a self indicator in the titration of oxalic acid?
Potassium permanganate is used as a self-indicator in the titration of oxalic acid because the initial pink color of potassium permanganate is decolorized in the presence of oxalic acid due to its reducing properties. The endpoint of the titration is reached when all the oxalic acid has reacted with the potassium permanganate, causing the pink color to persist. This change in color helps in determining the equivalence point of the titration.
What type of indicator is used during potassium permanganate titration?
Usually there is no indicator needed in potassium permanganate titrations as there will be an excess of manganate ions in the conical flask, turning the solution from colourless to pale pink.
Why does HCl not used to acidify the media in potassium permanganate titration?
HCl is not used to acidify the media in potassium permanganate titration because it can react with potassium permanganate, which can interfere with the titration results. Sulfuric acid is usually preferred as it does not react with potassium permanganate and ensures accurate titration results.
Why is HCl not used as catalyst in the standardization of potassium permanganate?
HCl is not used as a catalyst in the standardization of potassium permanganate because it can react with permanganate ions, affecting the accuracy of the titration. The standardization process requires a neutral or slightly basic medium to ensure the permanganate titration proceeds correctly.
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 do you determine the end point of titration involving sodium oxalate and potassium permanganate?
The end point of the titration is typically determined by observing a color change. In the case of sodium oxalate and potassium permanganate, the permanganate ion is a deep purple color, and it will turn colorless once it has reacted completely with the oxalate ion. This color change indicates the end point of the titration.
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
How do you redox titration by Potassium Permanganate?
In a redox titration using potassium permanganate, the permanganate ion (MnO4-) acts as the oxidizing agent while the other substance being titrated acts as the reducing agent. The endpoint is reached when all the reducing agent has been consumed, leading to a color change from purple to colorless or light pink. The volume of potassium permanganate solution required to reach the endpoint is used to calculate the concentration of the reducing agent.
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.
Why do you add zinc metal during titration of ferrous oxalate and potassium permangnate?
Zinc metal is added during the titration of ferrous oxalate and potassium permanganate to ensure that all the permanganate ions are used to oxidize the ferrous ions and not any other substances present in the solution. The zinc reduces any excess permanganate ions to colorless Mn2+ ions, allowing for a more accurate determination of the endpoint of the titration.
Why is potassium permanganate used for most titrations?
Potassium permanganate is commonly used as a titrant due to its strong oxidative properties, allowing it to easily oxidize most organic and inorganic compounds. Its deep purple color also serves as a visible indicator to signal the endpoint of the titration. Additionally, it can be used in both acidic and basic environments, making it versatile for a wide range of titration reactions.
Why KmnO4 is used as self indicator?
As we all know that the potassium permanganate (KMnO4) is the dark purple color solution ...and in titration it become colorless ....so when the titration is completed ...and the other single drop of KMnO4 solution produce pinkish colour in a beaker ...which indicate that the reaction was completed just a single drop before .. we use indicator in a a reaction in order to indicate ...but we dont used indicator in titration with KMnO4 because it also indicate us by changing its color ...colorless to pink
