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.

How do you separate gold from a lead-gold mixture?
Use a bone ash cupel.. base metals oxidize and actually dissolve in the cupel. this works on lead especially, leaving a ball of precious metals to be seperated..or you could use aqua regia at boiling.. let cool and your lead chloride will fall as a white powder.. your gold chloride is left in the solution to be reduced..
What happens when zinc dust is added to an acidified solution of potassium permanganate?
KMno4 is reduced to Mn^2+ Salt and the pink colour is discharged by the nascent hydrogen produced when zinc reacts with h2so4
Why colour of ethanol changes when mix with potassium permanganate?
The purple color of the KMnO4 will change to a muddy brown.
What is the Reaction of cyclohexane with alkaline KMno4?
The reaction of cyclohexane with alkaline potassium permanganate is oxidation. This oxidation gives off the chemical cis-1,2-cyclohenanediol. The permanganate ion is reduced to green manganite.
Why colour changes to pink when mohr's salt solution is added to potassium permanganate solution?
because Mn gets reduced form +7 oxidation state to +2 oxidation state and oxidizes Fe ions from +2 To +3 state and N in +2 state is colourless or of link colour
What are correct regarding the reaction between potassium ferrocyanide and KMnO4 in acidic solution Permanganate ion is the oxidizing agent or Oxidized?
permanganate ion is an oxidising agent and is reduced.

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.

Why is there colour change in the reaction between oxalic acid and potassium permanganate?
The dark purple color of permanganate fades because during the reaction permanganate is reduced to manganese cations and water. The other reactants and products are not strongly colored.
Is chloride reduced?
yes
How you can separate iodine from salt?
The salt should be an Iodide salt. Put the iodide salt into concentrated sulfuric acid. This will oxidize iodide to elementary Iodine.I- + H2SO4 ----> I2 + SO2 + H2O + HSO4-Another way is treating iodide salt with Chlorine, which will oxidize iodide to iodine and chlorine will be reduced to chloride.2 I- + Cl2 ----> I2 + 2 Cl-

What role play oxidising agent in a reaction?
They oxidize the other substances by accepting electrons and are therefor reduced.
Why is potassium permanganate used in titration experiment despite being a secondary standard solution?
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
