What is the factor of potassium permanganate?
What is the factor of potassium permanganate?
n-factor is defined as the number of H + ions replaced by 1 mole of acid in a reaction. In neutral medium KMnO4 forms MnO2 (+7 to +4) i.e. it gains 3 electrons. So, n-factor= 3.

What are the uses of potassium permanganate?
Potassium permanganate is used as a wet dressing for wounds on your skin’s surface that are blistered or oozing pus. Athlete’s foot and impetigo. Potassium permanganate can help to treat both bacterial and fungal skin infections such as athlete’s foot and impetigo.
What is valency factor of potassium permanganate?
Valence factor/ n-factor : is defined as the change in oxidation state of a an atom in a compound per molecule. 3, The valence factor of KMnO4 is 5.
How do you find the valence factor?
Hint: $n$ factor or valency factor can be found by calculating how many equivalents of the product is formed per mole of the reactant. Thus, first we must find the number of equivalents of oxygen gas formed, and then divide it with the number of moles of the reactant to get the $n$ factor.
