This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!
KMnO4 will first be converted to manganate and subsequently to insoluble manganese dioxide when it is exposed to an alkaline solution.
In an alkaline environment, what kind of reaction does KMnO4 have?
The reaction that takes place when KMnO4 is exposed to an alkaline environment looks like this: 2KMnO4 + 2KOH > 2K2MnO4 + H2O + O.
What is the common name for dilute alkaline KMnO4?
Because potassium permanganate is such a powerful oxidizing agent, it has a propensity to steal electrons from the molecules of other substances. A purple solution is produced when it is dissolved in water. It has a pleasant taste and has no discernible odor. The manganese is in +7 oxidation state. Toppr has validated your answer.
Which of the following does not experience oxidation when exposed to alkaline KMnO4?
Even extremely strong oxidizing agents such as KMnO4 are unable to oxidize fluoride ions.
Is a reducing agent present in alkaline KMnO4?
Answer in full, with all steps included:
This molecule is an effective source of oxidation due to the fact that, as the oxidation states of the elements’ atoms grow, the elements themselves become more electronegative. Because potassium permanganate contains the anion MnO4-, it possesses powerful oxidizing characteristics. These properties are the result of potassium permanganate’s composition.
“MnO_(4)(-)” is converted into the following in an alkaline solution that is dilute:

What is the key distinction between alkaline KMnO4 and acidified KMnO4?
The carboxylic acid product will be directly produced when acidified KMnO4 is used. In contrast, alkaline KMnO4 will first produce the carboxylate salt, which will then need to be acidified in order to produce the carboxylic acid product. This process will take place in reverse order. Hence, acidified KMnO4 is all that is required to produce the product; there is no need for any other intermediary steps.
What function does the alkaline KMnO4 serve?
Because the oxidation state of permanganate rises in the presence of an acidic medium and because it possesses a +7 oxidation in anionic form, which makes it highly electronegative, we are aware that alkaline potassium permanganate is the oxidizing agent. As a result, it can convert alcoholic compounds to ketonic compounds.
Which of these substances cannot be oxidized when exposed to KMnO4?
Because KMnO4 generates the ion MnO4-, it cannot be oxidized by O3. This is because the Mn in the MnO4- ion is in the +VII oxidation state, which is the highest possible oxidation state for Mn. As a result, it is incapable of undergoing any more oxidation.
In an acidic media, which chemical will not be oxidized when exposed to KMnO4?
The chemical known as potassium permanganate is one that is resistant to oxidation by ozone (O3). During the separation process, KmnO4 is converted into K+ and MnO4 -. Due to the fact that MnO4 has the highest valency and can undergo oxidation in addition to other processes.
What byproduct is produced when iodine and manganese dioxide are oxidized in an alkaline environment?
Now that we’ve got that out of the way, let’s talk about the oxidation reaction that takes place when iodide ion is combined with permanganate ion…. In this instance, the oxidation state of manganese shifts from +5 to +2, which indicates that it is undergoing reduction. As a result of this reduction, it is able to convert the iodide ion of potassium iodide into the iodate ion of potassium iodate.
Is KMnO4 a basic or an acidic compound?
Potassium permanganate is a powerful oxidizing agent when it is exposed to an acidic media, but when it is exposed to a neutral or alkaline medium, it is a poor oxidant.
But-2-ene is subjected to what reaction when diluted alkaline KMnO4 is applied to it?
Vicinal glycols are produced when alkene has a reaction with a cold, dilute, or aqueous solution of potassium permanganate, which is also known as Beyer’s reagent. In conclusion, the interaction of but-2-ene with potassium permanganate oxidizes the chemical, which ultimately leads to the creation of two molecules of ethanoic acid.
Is KMnO4 a substance that oxidizes or one that reduces?
Potassium permanganate, often known as KMnO4, is a strong oxidizing agent that has a variety of applications in the field of organic chemistry.
What effect does a neutral environment have on KMnO4?
In contrast, it is reduced to the brown +4 oxidation state of manganese dioxide MnO2 when placed in an environment with a neutral pH.
What changes occur to KMnO4 when it is exposed to an acidic medium?
Potassium permanganate is a powerful oxidizing agent when it is exposed to an acidic media, but when it is exposed to a neutral or alkaline medium, it is a poor oxidant. Potassium permanganate quickly loses its color when exposed to strong acids like sulfuric acid. The effect of potassium permanganate is diminished gradually in weak acids like acetic acid.
As an oxidizing agent, why is KMnO4 used?
Why? When there is a greater difference between the oxidation states of atoms, the elements become more electronegative. Because of this, permanganate is an effective oxidizing agent.
Does H2O2 Have the Ability to Decolorize KMnO4?
[SOLVED] When H2O2 is added to acidified KMnO4, the substance changes color and becomes less yellow.
Which does not cause the KMnO4 solution to lose its color?
- Sulphur dioxide. 12%
- Ferric chloride. 44%
- Hydrogen peroxide. 23%
- Ferrous sulphate. 21%
Which of these will not cause KMnO4 to lose its color?
In FeCl3, iron is in its most oxidized state, Fe+3, and can therefore function only as an oxidizing agent; as a result, it does not decolorize an acidified solution of potassium permanganate (KMnO4).
Which of these substances is not suitable for use as a reducing agent?
possesses fluorine that is in the oxidation state 0, which indicates that it cannot transition to any higher oxidation state since it does not possess a stable oxidation state that is greater than 0, which indicates that oxidation state 0 is its maximum possible state. As a result, it is unable to function as a reducing agent because it cannot undergo any further oxidation.
Is it possible for O3 to oxidize KI?
Hint:Ozone or ${O_3}$ is an oxidizing agent. … Full step-by-step answer:Ozone and potassium iodide are the two substances that have been provided to us. Ozone is an oxidizing agent that can be found in the atmosphere. In a reaction with potassium iodide, ozone ends up reducing itself while at the same time oxidizing the potassium iodide.
Which one of these won’t be oxidized when exposed to ozone?
It is not possible for O3 to further oxidize KMnO4. It contains manganese in an oxidation state that is the maximum possible, +7. The oxidation of alkaline KI results in the formation of potassium iodate and periodate.
What is the result of adding just a few drops of alkaline KMnO4 to the ethanol?
It is common knowledge that alkaline [textKMntextO_4] is a powerful oxidizing agent; hence, it will oxidize ethanol first…. Hence, the color of potassium permanganate vanishes from a solution of ethanol after an alkaline compound called KMnO4 has been added to the mixture and the mixture has been slightly heated.
What side effects does the addition of alkaline KMnO4 to propanol have?
It is possible to oxidize propanol into propanoic acid by heating it with an alkaline potassium permanganate solution, or by heating it with an acidified potassium dichromate solution.
What results from the reaction between propanol and the alkaline KMnO4 compound?
Consequently, the formation of propanoic acid takes place during the heating of propanol in the presence of an alkaline potassium permanganate solution. When potassium permanganate is used to convert alcohol into acids, the color of the potassium permanganate does not go away.
