How acidified potassium permanganate is used as a reducing reagent?
Potassium permanganate is known as an oxidizing agent.
what is the equation for this aldehyde plus acidified potassium permanganate aldehyde plus Tollen's reagent aldehyde plus NaOH Cannaizarro's reaction aldehyde plus Fehling's rgt aldehyde plus Sodium H?
the equation for this are? aldehyde + acidified potassium permanganate RCHO + 2KMnO4 + H2SO4 → RCOOH + K2SO4 + 2MnO2 ↓+ H20 aldehyde + Tollen's reagent RCHO + 2AgNO3 + 2NH4OH → RCOOH + 2Ag↓ + 2NH4NO3 +H2O aldehyde+ Fehling's reagent RCHO + 2CuSO4 + 4NaOH →RCOOH + Cu2O↓+ 2Na2SO4 + 2H2O THAT's ALL I KNOW aldehyde + Sodium Hydrogen Sulfite
"Reaction with what other substance? It needs something to react with." Yes, it depends with what it is reacting.....but permanganate is a oxidative reagent, so it could possible oxidate others reagents, like carbon double bonds or triple bonds....if it is acidic solution, it´s more oxidant....it can break bonds and oxidate organic compounds.....it I think that the question is what happens when potassium permanganate (manganate VII) is heated. potassium permanganate + heat= potassium oxide + oxygen
Baeyer's reagent, named after the German organic chemist Adolf von Baeyer, is used in organic chemistry as a qualitative test for the presence of unsaturation, such as double bonds. Baeyer's reagent is an alkaline solution of cold potassium permanganate, which is a powerful oxidant making this a redox reaction.
What is the observation if to differentiate 2-butanone and 2-methylbutanal using Tollen's reagent and KMnO4?
ofcourse salicylic acid would react with Hot, acidic Potassium permanganate because it has a phenol group in its structure. and based in our chem, this kind of reagent is used to test the presence of phenol. to prove, or to give you a visible result, your finished product must change its color from purple to dark brown precipitate, this means that salicylic acid is already oxidized by the strong oxidizing agent.. *kuha mo?? anong hindi…
Potassium Permanganate will either add across a double bond,,,,,via a manganate ester intermediate to yield a syn diol........or if used under acidic conditions......warmed,,,,,,will oxidize primary alcohols to acids.....and secondary alcohols to ketones........by reaction with the OH group. The alkane lacks both these functional units,,,thus will be inert towards this reagent. Hope this helps. Dr Jim Romano CEO Orgoman.com...... CEO Romano Scientific New York
Sugars that can be oxidized by mild oxidizing agents are called reducing sugars (the oxidizing agent is reduced in the process) A non-reducing sugar is not oxidized by mild oxidizing agents (no reaction) Example of oxidising agent is Tollen's Reagent Simply put, reducing sugar will react with Tollen's Reagent while non-reducing sugar will not react with the mild oxidizing agent
Benedict's Regent Tests for Carbohydrates (monosacharides) Benedict's Reagent test for free aldehyde or ketone groups or Reducing Sugars in simple sugars. Benedict's Reagent contains Cupric ion (Cu^+2) and it will be reduced to Cuprous Oxide (Cu20) when it makes contact with the Reducing Sugars. The result will be a greenish brown to a reddish orange color.
Benedict's test is based on Benedict's reagent, a liquid that changes color based on the sugar content of the material put in. Ketohexose acts as a reducing sugar because benedict's reagent is comprised of sodium citrate, sodium carbonate, and cupric sulfate. The cupric sulfate reacts with the ketohexose, reducing it and causing it to precipitate as cuprous oxide, which is what changes the color of the reagent and determines the sugar content.
Benedict's solution, or Benedict's reagent, is a solution used for the analysis of reducing sugars. It may be qualitative or quantitave. The former is composed of copper sulphate, sodium carbonate and sodium citrate while the later additionally contains potassium ferrocyanide and potassium thiocyanate. The solution is so named after Stanley Rossiter Benedict, the scientist who created it.
take 3cm cubed of the carbohydrate and put in a test tube with 5cm cubed of benedict's reagent. If the carbohydrate is a reducing sugar the solution would turn red. If it contains a non- reducing sugar the solution would remain blue. Then take the non-reducing sugar boil it with dilute hydrochloric acid, cool it and neutralise it with sodium hydrogencarbonate and retest with benedict's reagent if the soultion turns red it means the non…
Non reducing sugars do not react with Benedict's reagent. After the test, sample without reducing sugars remains the same, blue. When reducing sugars are present in the sample, we can consider four results after the test is completed: a) green, low amount, that is 0.1 to 0.5% of reducing sugars in solution; b) yellow, low amounts of reducing sugars, 0.5 to 1.0%; c) orange, moderate content of reducing sugars, 1.0 to 1.5% of reducing sugars…
