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 is potassium permanganate not used as a primary standard?

Potassium permanganate is not used as a primary standard because it is hygroscopic, meaning it readily absorbs water from the atmosphere, leading to inaccuracies in measurements. Additionally, its high reactivity with organic compounds can cause side reactions, affecting the accuracy of the titration results. Finally, potassium permanganate has multiple oxidation states, making it difficult to determine its exact concentration in a solution, further limiting its suitability as a primary standard.


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 ferrous sulphate is not used in redox titration?

Ferrous sulfate is not used in redox titrations because it is easily oxidized by air in a laboratory setting, leading to inaccurate results. It is also easily hydrolyzed in the presence of water, affecting the stability and reliability of the titration. Alternative titrants with more stable and reliable properties, such as potassium permanganate or potassium dichromate, are preferred for redox titrations.


In permanganate titration's why is nitric acid not used?

Nitric acid is not used in permanganate titrations because it can react with permanganate ions and reduce them before they can oxidize the analyte. This interference can lead to inaccurate results in the titration process. Instead, sulfuric acid is often used as the acidifying agent in permanganate titrations.

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.


What will happen if hydrochloric acid is used instead of sulfuric acid in permanganometric titrations?

Hydrochloric acid will react with permanganate, but more violently than sulfuric acid, leading to inaccurate results. Additionally, hydrochloric acid will produce chlorine gas, which can be hazardous. It is best to use sulfuric acid for permanganometric titrations to ensure accurate and safe results.


How acidified potassium permanganate is used as a reducing reagent?

Acidified potassium permanganate can be used as a reducing agent by reacting with the oxidizing agent. The permanganate ion is reduced to manganese dioxide, manganese(II), or other manganese species, while the other species in the reaction is oxidized. The reaction is carried out in acidic conditions to prevent the decomposition of permanganate.


What indicators used in redox titration?

Some common indicators used in redox titrations are potassium permanganate (KMnO4), which changes color from purple to colorless in acidic conditions, and potassium dichromate (K2Cr2O7), which changes from orange to green in acidic conditions. Other indicators include starch-iodine complex and ferroin.


What is maximum wavelength of absorbance of potassium permanganate?

The maximum wavelength of absorbance for potassium permanganate is around 525 nanometers. At this wavelength, potassium permanganate exhibits a strong absorption peak due to its characteristic deep purple color. This absorption peak is often used in spectrophotometric analyses to quantify the concentration of potassium permanganate in solution.


Conclusion for the determination of iron by permanganate?

The conclusion for the determination of iron by permanganate is that oxidation of iron is one of the most popular titrations. All permanganate titrations, when used as a titrant, should use different techniques to read volume of liquid in the burette.
