initially it decolorizes bcoz it acts as oxidising agent so converts alcohol into acetic acid. later no change is found in KMnO4
bcoz all alcool is already cnverted into acetic acid.
The question is not clear , if it is for the combustion of ethanol then 25litre of oxygen is in large excess for 25 ml of ethanol.
A plant is destarched by placing a leaf under investigation in boiling water to get rid of all the excess starch. Then place into boiling ethanol to get rid of excess chlorophyll
Iodine is much more soluble in ethanol than in water, so it will usually form a homogeneous mixture. Of course, if you add more solid iodine than will dissolve in your quantity of ethanol at the temperature at which you are working, the excess solid will sink to the bottom. In that case, you have a heterogeneous mixture.
Excess urea in the body is primarily removed by the kidneys through urine excretion. Increasing fluid intake can help dilute urea levels and promote its excretion. In severe cases, dialysis may be necessary to remove excess urea from the blood.
Yes, iron tablets can cause urine to turn a greenish or yellow color. This is due to the way the body processes and eliminates excess iron. If you are concerned about changes in urine color after taking iron tablets, it is best to consult with a healthcare provider.

to shift the reaction toward the products (Benzocaine) to counteract the imposed change excess reactants so that will lead to a higher percentage of Benzocaine. according to Le Chatelier's principle
When potassium permagnate is added initially to ethanol, ethanol gets oxidised into ethanoic acid using potassium permagnate. Thus, decolorizing potassium permagnate. When excess is added , the color of potassium permagnate persists.
When ethanol reacts with excess acidified KMnO4, it is oxidized to form ethanoic acid. The purple color of KMnO4 is decolorized to colorless Mn2+ ions during the reaction.
Ethanol is the substance that, if consumed in excess, can cause intoxication.
Ethanol and water are miscible.
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.
Yes, citric acid neutralizes the severity of ethanol when it's consumed in excess.
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.
yellow
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.
