Why do you have to heat up the solution of oxalic acid after adding sulphuric acid for the titration with permanganate?

To act as a catalyst


Why are titrations using permanganate performed in an acid solution?

Titrations using permanganate ions are performed in acidic solutions because this will reduce KMnO4 completely to Mn2+.


How do you prepare standard solution of salicylic acid for siderophore estimation?

you get the right stuff


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.


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


What happen if the potassium permanganate solution drop to the water and add of concentrated sulfuric acid?

It will change colour and become purple


Why do you have to warm the oxalate solution before perfoming the tritration?

I am not sure about this answer.oxalic acid is the strong is acid it need atleast 60 degree or more so that potassium permanganate can give the pink colour.

What is the product of potassium permanganate and acetaldehyde?

what are the major product formed when ethanol reacts with acidified kmno4 solution


Is potassium permanganate acid or base?

No, its property is that it is that it is a strong oxidant (a source of Oxygen)


Acidified potassium permanganate reaction with toluene equation?

toluene is benzene with CH3 reacting this with KMnO4 in acidic solution will produce a benzene with a carboxylic acid (CH3 will be oxidized)
