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.
Potassium permanganate solution is purple in color.
The colour of aqueous potassium permanganate ranges from violet to lighter shades of purple depending on its concentration.Please see the related link below to see an image bench scale testing of potassium permaganate showing the range of colour that it can appear.
Potassium permanganate is a deep purple color, while potassium manganate VII is typically a green color.
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.

Potassium bromide dissolved in water appears as a colorless solution.
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.
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.

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.
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.
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.
When zinc dust is added to an acidified solution of potassium permanganate, a redox reaction takes place. The zinc reduces the permanganate ion, MnO4-, to form colorless manganese ions, while itself getting oxidized to zinc ions. The overall result is that the purple color of the permanganate solution fades as it is reduced.
