Potassium permanganate is colored because it absorbs light in the visible range of the electromagnetic spectrum. The permanganate ion is the source of the color, as a ligand-to-metal charge transfer takes place between the oxygen's p orbitals and the empty d-orbitals on the metal. This charge transfer takes place when a photon of light is absorbed, which leads to the purple color of the compound.

What does KMnO4 stands for?
It stands for Potassium Permanganate and is usually used to control color, taste, and odors.
What are kmno4?
acidicness number of kmno4
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 elements are in potassium permangante?
Potassium Hydroxide is KOH and potassium permanganate is KMnO4.

What is is the formula for potassium permanganate?
KMnO4.
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
