Why first colour changes when KMnO4 is added to ethanol and colour reappears when excess of KMno4 is added?
When KMnO4 is added to ethanol, it gets reduced to MnO2, causing the initial color change. However, when excess KMnO4 is added, MnO2 gets further oxidized back to KMnO4, resulting in the reappearance of the original color. This demonstrates the redox nature of the reaction between KMnO4 and ethanol.
How does fictional distillation differ from a simple distillation?
Fictional distillation is a conceptual process used in simulation and modeling to simplify the representation of complex distillation systems, often focusing on key components and behaviors without capturing all physical interactions. In contrast, simple distillation is a physical separation technique that utilizes differences in boiling points to separate components from a liquid mixture through heating and condensing. While fictional distillation aids in understanding and designing systems, simple distillation is an actual laboratory or industrial process.
What are kmno4?
acidicness number of kmno4
How many grams of KMnO4 should be used to prepare 2L of a 5M solution?
To prepare 2L of a 5M solution, you should put in 4.6575grams of KMnO4. It is important to make sure that you add them in that order. K should be added first, then Mn.
What is Valency of k in kmno4?
tell me about the vlance of Mn in KMnO4
What is the role of KMnO4 during the distillation?
Potassium permanganate (KMnO4) can be used during distillation to eliminate impurities and organic matter present in the distillate. It acts as an oxidizing agent, reacting with organic compounds to form carbon dioxide and water, thereby purifying the distillate. KMnO4 also helps in detecting the end point of distillation, as its color changes when excess KMnO4 is present in the distillate.
Why first colour changes when KMnO4 is added to ethanol and colour reappears when excess of KMno4 is added?

This demonstrates the redox nature of the reaction between KMnO4 and ethanol.
What colour change occurs when h2o2 is added to kmno4?
When hydrogen peroxide (H2O2) is added to potassium permanganate (KMnO4), the purple color of KMnO4 solution fades, turning into a colorless solution. This color change indicates the reduction of KMnO4 to Mn2+ ions.
difference between simple and fractional distillation?
The key difference between fractional and simple distillation is that fractional distillation is used when the components in the mixture have closer boiling points, while simple distillation is used when the components in the mixture have a large difference in their boiling points
What is the advantage of simple distillation to fractional distillation?
Whether it is better to use fractional or simple distillation depends on the liquids being separated and on the boiling points of the liquids. When there is a great difference between the boiling points of the liquids, simple distillation may be a better option. Likewise, if there is a small difference in boiling points, then fractional distillation is used.
Chemical symbol for permanganate?
The formula for potassium permanganate is KMnO4
How is simple distillation useful?

What is the basic setup required for a simple distillation process?
The basic setup for a simple distillation process includes a distillation flask, a distillation column, a condenser, a receiving flask, and a heat source. The mixture to be separated is heated in the distillation flask, and the vapors rise through the column where they condense in the condenser and are collected in the receiving flask.
Why acid is added in KMnO4 titration?
Acid is added in KMnO4 titration to provide an acidic medium, which helps to stabilize the oxidizing agent MnO4-. The acidic solution also helps to prevent the premature reduction of permanganate ions and ensures a clear endpoint in the titration by facilitating the reaction with the analyte.
In what situation would you use fractional distillation over simple distillation?
You would use simple distillation when the two products you are trying to separate have large difference in boiling points. Fractional distillation is needed when the two products have very close boiling points (like Hexane and toluene). In petroleum refining, the word "fractionation", not "fractional distillation" is used, often interchangeably with "distillation". When we have a crude mixture of different compounds which have very minor difference in their boiling points and cannot be separated simple distillation, then fractional distillation is used. Differenciation of components of petroleum is done by this process
Why kmno4 is added slowly in the titration?
KMnO4 is added slowly in titration to accurately determine the endpoint of the reaction. Rapid addition can lead to overshooting the endpoint, resulting in an inaccurate titration. Slow addition allows for better control and more precise determination of when the reaction is complete.
