What is the reaction between potassium permanganate and SO2?
This reaction is the following:2 KMnO4 + SO2 = 2 MnO2 + K2SO4
Show a reactionin which oxidizing agent is getting reduced and reducing agent is getting oxidised?
In the reaction between potassium permanganate (KMnO4) and hydrogen peroxide (H2O2), manganese in KMnO4 is reduced from +7 to +2 in the form of MnO2. The hydrogen peroxide is oxidized to water (H2O), where the oxygen in H2O2 goes from -1 to -2.
Why does KMnO4 catches fire when glycerine is added to it?
KMnO4 and glycerine undergo a vigorous oxidation/reduction reaction. KMnO4 is a very strong oxidizing agent, and when in contact with alcohols or poly hydroxy compounds, there is a strong reaction. With glycerol, it is 3 C3H5(OH)3 + 14 KMnO4 --> 14 MnO2 + 7 K2CO3 + 2 CO2 + 12 H2O.So, it is basically a combustion reaction of an organic triol, resulting in CO2 and H2O, and MnO2 as the reduced form of MnO4.
Why KmnO4 is used as self indicator?
As we all know that the potassium permanganate (KMnO4) is the dark purple color solution ...and in titration it become colorless ....so when the titration is completed ...and the other single drop of KMnO4 solution produce pinkish colour in a beaker ...which indicate that the reaction was completed just a single drop before .. we use indicator in a a reaction in order to indicate ...but we dont used indicator in titration with KMnO4 because it also indicate us by changing its color ...colorless to pink
Before reaction of kmno4 with oxalic acid why the reaction is slow and after reaction very fast why?
Before the reaction of KMnO4 with oxalic acid, the reaction is slow because the activation energy required for the reaction to proceed is high. However, once the reaction starts and the first few molecules react to form products, the activation energy decreases significantly, making it easier for subsequent molecules to react. This results in a faster reaction rate after the initial slow phase.
Why HCL is not use to acidify KMnO4 soln in permanganometric titration?
HCl cannot be used to acidify KMnO4 solution in permanganometric titration because it will react with KMnO4 reducing it to MnO2, which interferes with the titration process and affects the accuracy of the results. Instead, dilute sulfuric acid (H2SO4) is typically used to acidify the KMnO4 solution, as it does not interfere with the redox reaction between KMnO4 and the analyte.
Why you add h2so4 to the kmno4 titration?
consider the balance chemical equation, suppose the reaction with oxalic acid 2MnO4- + 16H+ + 5C2O4 --> 2Mn+2 + 8H2O + 10CO2 Above reaction shows that the reaction requires a number of protons to occur, H2SO4 is the source of these protons.
Which element is reduced in this reaction 2hcl plus 2kmno4 plus 3h2c2o4-6co2 plus 2mno2 plus 2kcl plus 4h2o?
In the given reaction, the manganese atom changes from a +7 oxidation state in potassium permanganate (KMnO4) to a +4 oxidation state in manganese dioxide (MnO2), indicating that the manganese atom is reduced.
What is the reaction of alkenes with KMnO4?
When alkenes react with KMnO4, they undergo oxidation to form diols or glycols.
What is the equation of Heptane KMnO4?
no reaction equation
WHAT IS THE MEDIUM FOR CONVERTING KMnO4 TO K2MnO4?
In order to convert KMnO4 to K2MnO4, a reducing agent is typically needed. One common method involves using a reducing agent like a metal, such as zinc or iron, to react with KMnO4 in an acidic medium to produce K2MnO4.
What happens when you mix naoh sugar kmno4 in water?
When you mix NaOH (sodium hydroxide), sugar, and KMnO4 (potassium permanganate) in water, a reaction can occur. The sugar will likely react with KMnO4, reducing it to a different oxidation state, while NaOH can also react with the sugar. This reaction could potentially release heat and produce various intermediate compounds and products. It is crucial to handle these chemicals with care as they can be potentially hazardous.
Rank these items in order of increasing oxidation number for manganese MnCl2 Mn KMnO4 Mno2 lowest oxidation number?
MnCl2: oxidation number +2MnO2: oxidation number +4KMnO4: oxidation number +7
Why glacial acetic acid is dangerous with KMnO4?
Glacial acetic acid is a concentrated form of acetic acid, which is a reducing agent. When mixed with potassium permanganate (KMnO4), which is an oxidizing agent, a vigorous reaction can occur, resulting in the release of heat, gas, and potentially causing a fire or explosion. This reaction is dangerous and should be avoided.
What is the reaction between KMnO4 and H2O2?
The reaction between KMnO4 (potassium permanganate) and H2O2 (hydrogen peroxide) is a redox reaction where the permanganate ion is reduced to manganese dioxide and oxygen gas is produced. The overall reaction can be represented as: 2 KMnO4 3 H2O2 - 2 MnO2 2 KOH 2 H2O 3 O2
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.
Can you draw the organic products formed from the reaction of 1-methylcyclohexene with KMnO4?
The reaction of 1-methylcyclohexene with KMnO4 forms 1-methylcyclohexan-1,2-diol and 1-methylcyclohexan-1,2-dione as the organic products.
