Why acid is added in KMnO4 titration?
as kmno4 acts as a strong reducing agent only in acid medium
Why in titration of kmno4 no indicator is used?
Because KMnO4 is an internal indicator.. No need to have any indicator.. it has distinctly different colour when it is reduced
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
What mass of KMnO4 is required to prepare 3.00 liters of a 0.05253 M solution of KMnO4?
24 g
What is formed in the titration of FeCl2 with KMnO4 with H2SO4 present?
FeCl2 + 2KMnO4 --> Fe(MnO4)2 + 2KCl
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.
Why oxalic acid is heated before titration with KMnO4?
Oxalic acid is generally warmed slightly because it is not completely soluble and heat helps this. It aids in accuracy of the titration.
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
A certain amount of hydrogen peroxide was dissolved in 100 ml of water and then titrated with 1.68m kmno4 how much h2o2 was dissolved if the titration required 22.3 ml of the kmno4 solution?
Mass of H2O2 = 0.637 g
How do you prepare 100 ml of 1 in 1000 KMnO4?
700gram = 0.7 kilogram
What is the difference between titration and standardization?
we know the concentration of standardization solution .eg (oxalic acid , mgso4 much more )but wo donot know the concetration of titration solution eg (kmno4 ,EDTA )
How many grams of KMnO4 should be used to prepare 2L of a 5M solution?
To prepare 2L of a 5M solution, you should put in 4.6575grams of KMnO4. It is important to make sure that you add them in that order. K should be added first, then Mn.
