The color of potassium permanganate does not disappear when excess is added because it is a self-indicating compound. When there is excess potassium permanganate present, it remains in its colored form (purple) to signal that the reaction is complete or that there are no reducers left to interact with.

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 cannot fully reduce potassium permanganate. While ethanol can partially reduce potassium permanganate to form manganese dioxide, the color remains because there is still some potassium permanganate present in the solution.
Does the colour of potassium permanganate persist when it is added initialy to heated 3ml of ethanol?
Initially, potassium permanganate added to heated ethanol would turn purple due to its characteristic color. However, as the reaction progresses and the ethanol is oxidized, the color of potassium permanganate will eventually disappear as it reacts with the ethanol.
What type of indicator is used during potassium permanganate titration?
Potassium permanganate (KMnO4) titration is typically used as a redox indicator. The endpoint is indicated by a color change from pink to colorless or clear.
Why the color of potassium perpanganate disappears if it is added to warm solution of ethanol?
The color of potassium permanganate disappears in a warm solution of ethanol due to the reduction reaction occurring between the permanganate ion (MnO4-) and the ethanol. This reduction reaction results in the formation of colorless manganese dioxide (MnO2) and other products.
How Potassium permanganate is use for purifying drinking water?
Potassium permanganate can be used for purifying drinking water by acting as a strong oxidizing agent to eliminate organic compounds, iron, and other impurities. By adding a small amount of potassium permanganate to water, it can help remove bacteria and odors, making the water safer to drink. However, it is important to use the correct dosage to avoid any negative health effects from excess intake of potassium permanganate.

Why no use indicator in the standardizing potassium permanganate titration?
In the standardization of potassium permanganate titration, an indicator is not used because the titration is self-indicating. This means the solution being titrated changes color at the end point, so an additional indicator is not necessary. It is important to carefully observe the color change to ensure accurate titration results.
Why do you add zinc metal during titration of ferrous oxalate and potassium permangnate?
Zinc metal is added during the titration of ferrous oxalate and potassium permanganate to ensure that all the permanganate ions are used to oxidize the ferrous ions and not any other substances present in the solution. The zinc reduces any excess permanganate ions to colorless Mn2+ ions, allowing for a more accurate determination of the endpoint of the titration.
What colour change is seen when excess potassium iodine is reacted with chlorine?
When excess potassium iodide is reacted with chlorine, the solution changes from colorless to dark brown due to the formation of Iodine (I2). Excess potassium iodide reacts with chlorine to form iodine, which imparts the dark brown color to the solution.
Add an excess of potassium iodide to copper sulphate solution how much is excess?
The amount of excess potassium iodide depends on the stoichiometry of the reaction between potassium iodide and copper sulfate. One equivalent of potassium iodide is needed to react with one equivalent of copper sulfate. Excess potassium iodide would be any amount added beyond this stoichiometric ratio.
Does the colour of potassium permanganate persist when it is added initially?
Not specifically the progress of the purple is caused by flow that was already happening in the water when the crystals were added. Adding the crystal itself only causes a small amount of local disturbance.
What is the name for excretion of potassium in the urine?
The excretion of potassium in the urine is known as kaliuresis. This process helps regulate potassium levels in the body by removing excess potassium from the bloodstream.
Excess potassium ion is eliminated from the body by?
Excess potassium ion is primarily eliminated from the body through the kidneys via urine. Additionally, a small amount of potassium can be excreted through sweat. It's important for proper kidney function to maintain the balance of potassium levels in the body.
