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 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 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.
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.
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 no use indicator in the standardizing potassium permanganate titration?
In the standardization of potassium permanganate titration, an indicator is not used because the titration is self-indicating. This means the solution being titrated changes color at the end point, so an additional indicator is not necessary. It is important to carefully observe the color change to ensure accurate titration results.

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.
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.
Which one is better for titration with Ferrous Ammonium Sulphate potassium dichromate or potassium permaganate and why?
Potassium dichromate is better for titration with ferrous ammonium sulfate because it reacts with ferrous ions in a 1:6 ratio, making it easier to determine the equivalence point accurately. Potassium permanganate, on the other hand, reacts with ferrous ions in a 1:5 ratio, which can lead to less precise results and requires a more careful technique.
Why you use dilute H2SO4 in titration permanganat and oxalic acid?
Dilute sulfuric acid is used in the titration of potassium permanganate with oxalic acid because it helps to maintain a stable pH and prevents the oxidation of oxalic acid by permanganate ions. This ensures accurate results by minimizing side reactions and interference.
How is oxalic acid vs NaOH titration different from oxalic acid vs potassium permegnate titration?
In the titration of oxalic acid with NaOH, the acid-base reaction involves the neutralization of the acid by the base. However, in the titration of oxalic acid with potassium permanganate, the permanganate ion oxidizes the oxalic acid to carbon dioxide. This difference in reaction mechanisms leads to different equivalence points and color changes in the two titrations.
Titration involving bismuth sulfate and Titration involving mercuric nitrate?
Titration involving bismuth sulfate would typically be used to determine the concentration of a solution of a known or unknown substance that can react with bismuth ions. On the other hand, titration involving mercuric nitrate would be suited for determining the concentration of substances that can react with mercuric ions. Each titration method is specific to the ions involved and the chemical reactions occurring.
What is the mechanism of the redox reaction between potassium permanganate and hydrogen peroxide?
The redox reaction between potassium permanganate and hydrogen peroxide involves the transfer of electrons. In this reaction, potassium permanganate acts as an oxidizing agent, while hydrogen peroxide acts as a reducing agent. The permanganate ion (MnO4-) is reduced to manganese dioxide (MnO2), while hydrogen peroxide is oxidized to water and oxygen gas. This reaction occurs in an acidic solution and is often used as a titration method in analytical chemistry.
