What element is responsible for the purple color in KMnO4?
Manganese (Mn) is responsible for the purple color in KMnO4. When potassium permanganate is dissolved in water, it dissociates into potassium ions and manganese ions, giving the solution its distinct purple hue.
What chemical is burning when you see a violet purple flame?
When you see a violet-purple flame, it often indicates the presence of potassium compounds, such as potassium chloride or potassium nitrate. The specific element responsible for the color is potassium.
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 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 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.

What are examples of purple colored elements on the periodic table?
The only [element I know of that's purple in its elemental form is iodine. Transition metal ions can be purple as well (for example, Mn +7 is responsible for the color of potassium permanganate).
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 colour of ethanol changes when mix with potassium permanganate?

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.
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.
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.
Is pottasium permanganate a crystal?
Yes, potassium permanganate is a purple crystalline solid at room temperature.
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 colours are being absorbed by purple permanganate in a spectro?
Purple potassium permanganate absorbs green and yellow wavelengths of light in a spectrophotometer, resulting in its characteristic purple color.
Why is there colour change in the reaction between oxalic acid and potassium permanganate?
The color change in the reaction between oxalic acid and potassium permanganate is due to the reduction of purple potassium permanganate (MnO4-) to colorless manganese dioxide (MnO2). This reduction reaction causes the change in color from purple to colorless.
