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.
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.
What colour is potassium permanganate potassium manganate VII?
Potassium permanganate is a deep purple color, while potassium manganate VII is typically a green color.
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 water become coloured when crystals of potassium permanganate are added to it?
Water turns colored when potassium permanganate is added because the potassium permanganate crystals dissolve, releasing the purple permanganate ion (MnO4-) into the water. The permanganate ion absorbs light in the visible spectrum, giving the water a pink or purple color.

Why Potassium permanganate act as self indicator?
as it is pink in colour so no external agent is required for titration when we titrate againist another component it will changes it colour to pale pink asd it is end point
What colour is potassium permanganate potassium manganate VII?
Potassium permanganate is a deep purple color, while potassium manganate VII is typically a green color.

How does acidic potassium permanganate react with ki?
Permanganate(purple) becomes Mn2+(pale pink) and Iodide becomes Iodine.
Why does the purple colour spread when a crystal of potassium permanganate is placed in water?
The purple color spreads when a crystal of potassium permanganate is placed in water due to the dissolution of potassium permanganate molecules in water. Potassium permanganate is a highly soluble compound, and its purple color comes from the permanganate ions in the crystal dispersing in the water. This dispersion allows the purple color to be visible throughout the water.
What happen if the potassium permanganate solution drop to the water?
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.
What is the colour of potassium permanganate solution?
The color is a very strong and deep purple color when concentrated and pinkish in very low concentration.
Why potassium permanganate is used as a self indicator in the titration of oxalic acid?
Potassium permanganate is used as a self-indicator in the titration of oxalic acid because the initial pink color of potassium permanganate is decolorized in the presence of oxalic acid due to its reducing properties. The endpoint of the titration is reached when all the oxalic acid has reacted with the potassium permanganate, causing the pink color to persist. This change in color helps in determining the equivalence point of the titration.
What type of indicator is used during potassium permanganate titration?
Usually there is no indicator needed in potassium permanganate titrations as there will be an excess of manganate ions in the conical flask, turning the solution from colourless to pale pink.
