I don't quite understand the question, so I'll just cover as much as I can.
#KMnO_"4"#, also known as Potassium permanganate, is a potassium salt, meaning it is an ionic compound from the product of a neutralization reaction between an acid and a base. The neutralization indicates its electrical charge as neutral.
It is commonly used as an oxidation agent, meaning it participates in the redox reactions, and is the agent gaining electrons. It is because of this property that #KMnO_"4"# is mainly used for, oxidation reactions.
The solid state of #KMnO_"4"# is a dark purple, however when dissolved in water, it transforms into a pink solution.
#K =# Potassium,
#MnO_"4"=# permanganate, a polyatomic ion which by itself, has an ionic charge of 2-.
It's physical properties can be googled simply by searching "physical properties of #KMnO_"4"#" so I won't talk about that.
Hope this helps :)
