Potassium permanganate solutions due to the strong oxiding nature readily forms MnO2 on contact with impurities. Traditionally sources of KMnO4 always contained traces of MnO2 . KMnO4 solutions "go off" when they stand for a period.

Chemical symbol for permanganate?
The formula for potassium permanganate is KMnO4
What is the chemical formula for Condys Crystals?
Formula: KMnO4
What is the mass of 2.55 mol of KMnO4?
Number of moles= Mass/molar mass (g/mol) Hence Mass= mol × molar mass Mol=2.55 Molar mass of KMnO4= 39+55+(16×4)= 158g/mol Where K=39, Mn=55 and O =16 Hence Mass of KMnO4 in 2.55 mols of the compound= 2.55×158= 402.9g.
Is hcl praimary standard or secondary standard?
HCl is not used as a primary standard
Why does alkene reacts kmno4?
KMnO4 will react with compounds having unsaturation (double bond or triple bond). Since alkenes have double bond, it will react with KMnO4 and decolourize dilute KMnO4 solution.

What are kmno4?
acidicness number of kmno4
What is is the formula for potassium permanganate?
KMnO4.
What is secondary standard apparatus What are secondary apparatus?
one is specific
How many grams of potassium permanganate KMnO4 are in 2.55 moles?
The compound potassium permanganate has chemical formula KMnO4 Molecular mass of KMnO4 = 39.1 + 54.9 + 4(16.0) = 158.0 Mass of KMnO4 = amount of KMnO4 x Molecular mass of KMnO4 = 2.55 x 158.0 = 403g
What elements are in potassium permangante?
Potassium Hydroxide is KOH and potassium permanganate is KMnO4.
What is Valency of k in kmno4?
tell me about the vlance of Mn in KMnO4

Why is potassium permanganate used in titration experiment despite being a secondary standard solution?
kmno4 is very good oxidizing agent. that means it is easily reduced by any other reagent. so it can't be considered as primary standard as its concentration changes upon free leaving
