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!
According to my understanding, KMnO4 should be a more effective oxidizing agent in an acidic solution as opposed to an alkaline medium. In an acidic solution, it converts iodide, which has an oxidation state of -1, to iodine, whereas in an alkaline medium, it converts iodide, which has an oxidation state of -1, to iodate, which has a charge of +5.
If alkaline KMnO4 is treated with KI, the iodide ion in the compound is oxidized to what?
Extra information is as follows: In the reaction described above, potassium permanganate (KMnO4) acted as an oxidizing agent because it converted the iodide ion (I) into an iodine molecule, whereas potassium iodide (KI) acted as a reducing agent because it converted potassium permanganate (KMnO4) into magnesium sulphate (MnSO4).
Iodine is converted into what substance when it is exposed to KMnO4 in an alkaline environment?
In an alkaline environment, KMnO4 functions as an oxidizing agent. Iodide ion is converted to IO3- through the process of alkaline KMnO4 being treated with KI.
What does the conversion of alkaline medium KMnO4 produce?
KMnO4 will first be converted to manganate and subsequently to insoluble manganese dioxide when it is exposed to an alkaline solution.
Is an oxidizing agent present in alkaline KMnO4?
Dilute alkaline KMnO4 is: A. a substance that promotes oxidation… In the field of organic chemistry, potassium permanganate in an alkaline solution is utilized to oxidize hydrocarbons into alcohol, which is subsequently converted into an aldehyde or ketone, and eventually into a carboxylic acid.

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 is the key distinction between acidic KMnO4 and alkaline KMnO4?
Since oxidation in a very alkaline solution only results in the reduction of permanganate to manganate(VI), this type of reaction is the least effective in terms of the number of electrons that are transferred per mole of permanganate. Despite this, oxidation in an acidic medium is often favored, particularly for the reasons discussed above and for substrates that are easily damaged by strong bases.
What changes occur to KMnO4 when it is exposed to an acidic medium?
When dissolved in an acidic solution, permanganate(VII) undergoes a reduction process that causes it to take on the rosy pink +2 oxidation state of the manganese(II) (Mn2+) ion. In contrast, it is reduced to the brown +4 oxidation state of manganese dioxide MnO2 when placed in an environment with a neutral pH.
Why is KMnO4 used when the medium is acidic?
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.
What is the name for the alkaline form of KMnO4?
Bayer’s reagent is an alkaline potassium permanganate (KMnO4) solution…. Bayer’s reagent is used to… Alkenes and alkynes can both be oxidized with Baeyer’s reagent.
Which of the following is oxidized by alkaline KMnO4?
D) Salicylic acid. Hint: Alkaline potassium permanganate oxidizes benzene side chain. Aliphatic group describes the die chain of the benzene molecule. It does not matter how many carbon atoms are contained in the benzene size chain because the benzene will still be oxidized to aromatic carboxylic groups.
What is the oxidation number shift that occurs in potassium permanganate when it is exposed to strong alkaline medium?
+7 is the oxidation state that the manganese atom has in KMnO4.
When compared to the weight of KMnO4 in acidic, alkaline, and neutral mediums, what is the corresponding weight?
In an acidic medium, the KMnO4 has an equivalent mass of 31.6, while in an alkaline medium, it has a mass of 52.7.
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.
Why does KMnO4 act as an indication even when it is already present?
KMnO4 solutions are dark purple. When this substance is put to use as a titrant, as soon as the endpoint is reached and there is an excess of KMnO4-, the solution takes on a color that is invariably pink. As a result, KMnO4 is capable of serving as its own indication.
When a solution of KMnO4 is put to heated oxalic acid, what happens?
When a solution of KMnO4 is introduced to a solution of oxalic acid, the decolorization occurs gradually at first but then happens almost instantly after some time has passed because of this.
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.
On but-2-ene, what effect does an acidic solution of KMnO4 have?
The reaction of acidic KMnO with but-2-ene results in the formation of acetic acid, chemical formula CH COOH. Potassium permanganate, sometimes known as KMnO, is an extremely powerful oxidizer. This causes the double bond to be broken, and the resulting fragment is converted into acetic acid (CH COOH).
What kinds of reactions can KMnO4 have?
In an alkaline solution, KMnO4 will spontaneously reduce to the green compound K2MnO4; in this compound, manganese will be in the +6 oxidation state. When strong sulfuric acid is added to potassium permanganate, a peculiar reaction takes place. Mn2O7, which has the potential to explode, is produced when concentrated sulfuric acid combines with KMnO4.
Is KMnO4 unstable in acidic medium?
When placed in an acidic media, its solution becomes unstable.
Why is sulfur dioxide a more effective reducing agent in an alkaline medium?
Because hydrogen ions are not present in alkaline media, the reaction described above proceeds in the opposite direction. As a result, sulphur dioxide is a more potent reducing agent in alkaline medium than it is in acidic medium.
What does KmnO4 do to alkanes?
There is no reaction between alkanes and aromatic compounds when potassium permanganate is present.
To differentiate what, exactly, does alkaline KmnO4 serve?
The alkaline potassium permanganate test is utilized in the qualitative organic analysis to identify the presence of unsaturation chemicals such as alkyne and alkene…. An oxidizing agent is provided by the element potassium permanganate in the course of this reaction.
What results from the reaction of ethylene with the alkaline compound KmnO4?
Answer in full, with all steps included:
In the presence of alkaline potassium permanganate, ethylene or ethene will undergo a reaction that will produce either ethane-1,2-diol or ethylene glycol. It is known as the hydroxylation reaction because the product of the interaction between ethylene and alkaline KmnO4 is hydroxyl groups that have been formed across the double bond.
