Potassium permanganate is not used as a primary standard because its purity can be affected by air oxidation, making accurate titrations difficult. It is more commonly used as a secondary standard in analytical chemistry for redox titrations due to its strong oxidizing properties and distinct color changes.
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.
The primary standard commonly used to titrate against potassium hydroxide is potassium hydrogen phthalate (KHP). It is a stable compound with a well-defined molar mass, making it suitable for accurately determining the concentration of a solution of potassium hydroxide.
Well, hello there, friend! Potassium permanganate (KMnO4) is often used as a secondary standard because it can be easily prepared to a high level of purity. Its rich purple color makes it easy to spot the endpoint of a titration, which is quite handy in the lab. Just like a happy little tree in a painting, KMnO4 brings a sense of reliability and consistency to chemical analysis.
Potassium permanganate (KMnO4) is a dark purple, crystalline compound that is commonly used as an oxidizing agent in various chemical reactions. It is soluble in water and known for its powerful oxidizing properties.
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.
Iodine is not directly employed as a primary standard because it is less stable in solution compared to other primary standards like potassium dichromate or potassium permanganate. Additionally, iodine is sensitive to light and air, leading to potential degradation and affecting its accuracy as a primary standard.

kmno4 is very good oxidizing agent. that means it is easily reduced by any other reagent. so it can't be considered as primary standard as its concentration changes upon free leaving
Potassium permanganate can be used in chicken diseases. It is commonly used as a simple remedy for purposes of treating diarrhea.

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.
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.
If potassium permanganate solution is dropped into water, it will dissolve and create a purple or pink solution. Potassium permanganate is a strong oxidizing agent and can be used for various applications such as disinfection and water treatment.
