Why is permanganate estimation completed in acid?
it provides the H+ ions to catalyse the reaction
Why are titrations using permanganate performed in an acid solution?
Titrations using permanganate are performed in an acid solution to prevent the premature oxidation of permanganate. Acidic conditions stabilize permanganate in its purple form until it reacts with the analyte, ensuring accurate titration results.
Which of the following might you use to titrate an oxalic acid solution?
You could use a standardized solution of potassium permanganate (KMnO4) to titrate an oxalic acid solution. Potassium permanganate is a strong oxidizing agent that reacts with oxalic acid in an acidic medium, forming carbon dioxide gas, manganese dioxide, and water.
What is the reaction between sulphamic acid with sodium hydroxide in paracetamol estimation?
In the reaction between sulphamic acid and sodium hydroxide in paracetamol estimation, sulphamic acid reacts with paracetamol to form a colorless solution. The addition of sodium hydroxide then helps to break down the paracetamol into its constituent components, allowing for accurate estimation of the amount present in the solution.
Can permanganate ions oxidize the chloride ion to Cl2 and be reduced to Mn2 plus in acidic solution?
Purple permanganate ion is reduced and almost decolorized (to Mn(II)) by chloride ion in acid solution. Purple permanganate ion is reduced to green manganate ion by chloride ion in basic solution. In neutral chloride solution, there is no reaction.Source: UW Card Catalog

How do you prepare standard solution of salicylic acid for siderophore estimation?
you get the right stuff
What happen if the potassium permanganate solution drop to the water and add of concentrated sulfuric acid?
When potassium permanganate solution is dropped into water, it dissolves and forms a purple solution. If concentrated sulfuric acid is then added, the manganese in potassium permanganate can be reduced to form a colorless compound. This reaction generates heat and can be exothermic. The resulting solution will likely be colorless or have a faint pink hue instead of the original purple color.
What is the importance of boiling KMnO4 solution if it is for future use?
If the potassium permanganate solution is prepared from stock solid potassium permanganate, it is important to remove manganese dioxide from the system. MnO2 catalytically decomposes permanganate into oxygen and lower ox. states manganese. Manganese dioxide is insoluble, whereas permanganate is very soluble. Boiling the solution would ensure that all solid permanganate had dissolved, and so little would be lost upon filtering out MnO2 (which remains insoluble at higher temperatures) The remaining solution will have a longer shelf-life due to the absence of the aforementioned decomposition catalyst. If the permanganate solution is required acidic, the use of a small amount of phosphoric acid can be effective. Typically, sulfuric acid is used in combination with permanganate as an acid oxidant. The problem being that sulfuric acid dissolves manganese and thus the catalyst becomes soluble, and difficult to remove. Stock acid solutions of permanganate have far reduced shelf-life. The addition of a small amount of phosphoric acid helps alleviate this. Manganese(ii) oxide reacts with acidified permanganate to form Manganese(iii) cations - these in turn precipitate from solution as manganese(iii)phosphate. Complex ions of manganese(iii) can also form with phosphate, and these partake roles in equilibrium resulting in their further deposition from solution. Once the phosphate complexes are removed by filtration of the hot acidified permanganate solution, the solution has a longer shelf-life.

Which compound give brown precipitate with alkaline potassium per mangnate solution?
Ferrous chloride in presence of hydrochloric acid gives brown precipitates of Ferric chloride with potassium permanganate.
What happens when potassium permanganate is standardized with ethanedioic acid?
When potassium permaganate is mixed with ethanedioc acid the potassium permanganate Mn04- ion will be converted toMn2+, this means that you will observe the purple colour changing to a clear solution and the permanganate ion is oxidised. The Mn2+ will act as an auto catalyst speeding up the reaction, therefore a funny rate will occur, where the reaction is slow to start, before speeding up and slowing down again at the end. I read about this in chemistry review, so you can check it out there...http://www.york.ac.uk/depts/chem/chemrev/autocat.doc.
