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.

Write the chemical reaction between cyclopentene and potassium permanganate?

cyclopentene reaction with potassium permanganate. If cyclohexene gives a diacid (two acid groups in a opened ring), I think that is should yield a pentane with two acid groups, one in each end....it could give more products like CO2 and H2O, by breaking the bonds, you could get a lot of compounds, depending which bonds could break.....


Why does the colour of potassium permanganate changes to brown when react with ethanol?

When potassium permanganate reacts with ethanol, it undergoes reduction, resulting in a color change from purple to brown. The purple color of potassium permanganate is due to the permanganate anion (MnO4-) in an alkaline medium, and when it is reduced by ethanol, it forms manganese dioxide (MnO2), which is brown in color.


What is the reaction of Potassium permanganate and salicylic acid?

ofcourse salicylic acid would react with Hot, acidic Potassium permanganate because it has a phenol group in its structure. and based in our chem, this kind of reagent is used to test the presence of phenol. to prove, or to give you a visible result, your finished product must change its color from purple to dark brown precipitate, this means that salicylic acid is already oxidized by the strong oxidizing agent.. *kuha mo?? anong hindi nagreact. imbento !


What is the reaction of iron sulphate solution with potassium permanganate?

The Mn+7 ions (purple) are reduced to Mn+4 ions (brown), unless some diltue sulfuric acid has been added to the solution. This will make the Mn+7 ions reduce fully to Mn+2 ions (colourless). The end point of the reaction is gotton when there is a permanent pale pink tinge left in the conical flask. (The Potassium Permangante should be in a Burette and be released slowly into the flask containing the Iron Sulfate). HOWEVER: Iron sulfate gets oxidised by Oxygen in air and water and undergoes hydroylisis of water. Therefore you should use a primary standard like Ammonium Iron II sulfate for this reaction.


Is the reaction between magnesium nitrate and potassium chromate chemical or physical what is the chemical equation for this reaction?

The reaction between magnesium nitrate and potassium chromate is a chemical reaction, as it involves the formation of new substances. The chemical equation for the reaction is: 2 Mg(NO3)2 + K2CrO4 -> MgCrO4 + 2 KNO3

Characteristics of reaction of lemon juice and potassium permanganate?

The reaction between lemon juice (containing citric acid) and potassium permanganate is a redox reaction. The purple color of the potassium permanganate fades as it gets reduced to colorless manganese(IV) oxide, while the citric acid gets oxidized to carbon dioxide and water. The reaction is exothermic and can be used to demonstrate redox reactions in chemistry experiments.


Why is the reaction between glycerol and potassium permanganate irreversible?

The reaction between glycerol and potassium permanganate is irreversible because it involves a complete change in the molecular structure of the reactants. Glycerol, an alcohol compound, is oxidized by potassium permanganate, resulting in the formation of different products, such as carbon dioxide, water, and manganese dioxide. Once these new products are formed, it is difficult to reverse the reaction and reform the original reactants.


Why is methylcyclopentanol does not change the colour of potassium permanganate?

Methylcyclopentanol does not change the color of potassium permanganate because it is not easily oxidizable by the permanganate ion. The structure of methylcyclopentanol does not provide the necessary functional groups or carbon-hydrogen bonds that can be readily oxidized by potassium permanganate.


Why does the color of potassium permanganate not disappear when excess of ethanol is added to it?

The color of potassium permanganate does not disappear when excess ethanol is added because ethanol is unable to fully reduce the permanganate ion (MnO4-) to colorless manganese dioxide (MnO2). Ethanol is a weak reducing agent and is not capable of completely reducing the permanganate ion in this reaction. Additionally, the reaction between potassium permanganate and ethanol is not stoichiometric, meaning that there is an excess of one of the reactants, which can also contribute to the color persisting.


Why colour of ethanol changes when mix with potassium permanganate?

When ethanol is mixed with potassium permanganate, the purple color of the potassium permanganate fades. This is because ethanol reduces the potassium permanganate to form manganese dioxide, which is a brown precipitate. As a result, the overall color of the solution changes from purple to brown.


Why does pattisum permangrate turn purple in water?

Potassium permanganate turns purple in water because it undergoes a reaction in the presence of water to form hydrated manganese dioxide, which is a purple compound. This change in color is due to the formation of the purple complex ion resulting from the reaction of potassium permanganate with water.

How a crystal potassium permanganate in a beaker change colour in water within minutes?

When potassium permanganate crystals are placed in water, they dissolve and release potassium and permanganate ions. These ions react with water molecules to form manganese dioxide, which gives the solution a pink or purple color. The rapid color change is due to the quick reaction of the ions with the water, causing the solution to turn vividly colored within minutes.


Why the color of potassium perpanganate disappears if it is added to warm solution of ethanol?

When potassium permanganate reacts with ethanol, it releases oxygen. ie, an atom of oxygen thus converting the ethanol to acetic acid. Initially colour disappears because coloured permanganate ions of potassium permanganate are consumed to oxidise ethanol. C 2 H 5 OH (WITH ALKALINE KMnO 4) CH 3 COOH+H 2 O Remember :When excess is added colour does not change because there is no more alcohol left and hence there is no reaction.


Another test for hexane and hexene apart from bromine?

Another test to differentiate between hexane and hexene is performing a reaction with potassium permanganate in acidic conditions. Hexane will not react with potassium permanganate, while hexene will undergo a color change as the double bond is oxidized by the permanganate ion.


What happens to the colour of water when potassium permanganate is added?

When potassium permanganate is added to water, the water changes color to a pink or purple hue. This is because potassium permanganate is a strong oxidizing agent that reacts with organic compounds present in the water, causing the color change.


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.
