In permanganate titration's why is nitric acid not used?
Nitric acid, being a strong oxidising agent, interferes with oxidising capacity of KMnO4 hence reducing accuracy of titration.
What happen when ethanol is heated with alkaline kmno4 solution?
When ethanol is added to alkaline KMno4 solution, the ethanol gets oxidised to ethanoic acid due to nascent oxygen. KMno4 is an oxidising agent. thus when we first add alkaline Kmno4 to ethanol, the pink colour of the Kmno4 vanishes, as it is being used up for the oxidation process. however. when all of the ethanol has been oxidised into ethanoic acid, and we keep adding Kmno4, the colour returns, as there is no more ethanol left to oxidise.
Why HCL is not use to acidify KMnO4 soln in permanganometric titration?
It is probably because a part of the oxygen produced from the reaction of KmnO4 and HCl is used up in oxidising the HCl to Cl2 gas
What chemicals can form brominea kmno4 b kbr or c h2so4 and d naoh?
Kbr
Why acid is added in KMnO4 titration?
as kmno4 acts as a strong reducing agent only in acid medium
What compounds is the strongest oxidising agent MnO2 K3MnO4 K2MnO4 KMnO4?
KMnO4 is the strongest oxidizer of these chemicals.

What are correct regarding the reaction between potassium ferrocyanide and KMnO4 in acidic solution Permanganate ion is the oxidizing agent or Oxidized?
permanganate ion is an oxidising agent and is reduced.
Which gas is evolved when KMnO4 reacts with H2C2O4?
The evolved gas is carbon dioxide (CO2).

Why first colour changes when KMnO4 is added to ethanol and colour reappears when excess of KMno4 is added?
initially it decolorizes bcoz it acts as oxidising agent so converts alcohol into acetic acid. later no change is found in KMnO4 bcoz all alcool is already cnverted into acetic acid.
Can someone help with this chemical equation K4FeC6N6 plus KMnO4 plus H2SO4 KHSO4 plus Fe2S3?
The balanced chemical equation would be K4FeC6N6 + KMnO4 + H2SO4 = KHSO4 + Fe2SO43 + MnSO4 + HNO3 + CO2 + H2O.

What is formed in the titration of FeCl2 with KMnO4 with H2SO4 present?
FeCl2 + 2KMnO4 --> Fe(MnO4)2 + 2KCl
Will KMnO4 react with NaCl?
yes since kmno4 is an oxidizing agent so it will reduce to mn2+ and the nacl cl will be oxidised to cl2.
