Yes, Potassium manganate(VII), K2MnO4 or Potassium permanganate is an oxidizing agent
Yes. Sodium permanganate is an ionic compound comprising mono-atomic sodium cations and polyatomic permanganate anions.
it is pinkish purple in color
Manganate(VII) ion is MnO42-
The color become pink; the cause is the formation of ions 2+.
Potassium Permanganate or Potassium Manganate (VII)
Yes, Potassium manganate(VII), K2MnO4 or Potassium permanganate is an oxidizing agent
KMnO4 is potassium permanganate.
Potassium manganate = K2MnO4 Potassium permanganate = KMnO4 It is important to quote the oxidation state of the compound. Potassium manganate could easily be potassium manganate (VI) as opposed to potassium manganate (VII) KMnO4 Potassium manganate (VI) K2MnO4 is a dark green compound made by fusing manganese (IV) oxide with potassium hydroxide. It is stable in basic solution In aqueous acidic solution it disproportionates to the manganate (VII) ion and manganese (IV) oxide.
Potassium Manganate (VII) also called potassium permanganate, dissolves very quickly in hot water and much slower in cold water.
Yes. Sodium permanganate is an ionic compound comprising mono-atomic sodium cations and polyatomic permanganate anions.
"Reaction with what other substance? It needs something to react with." Yes, it depends with what it is reacting.....but permanganate is a oxidative reagent, so it could possible oxidate others reagents, like carbon double bonds or triple bonds....if it is acidic solution, it´s more oxidant....it can break bonds and oxidate organic compounds.....itI think that the question is what happens when potassium permanganate (manganate VII) is heated.potassium permanganate + heat= potassium oxide + oxygen
it is pinkish purple in color
Manganate(VII) ion is MnO42-
The color become pink; the cause is the formation of ions 2+.
Potassium Dichromate (VI) can be acidified with sulphuric acid AND hydrochloric acid! Note that another common oxidising agent ' Acidified Potassium Manganate (VII)' is sometimes used although this one can only be acidified with sulphuric acid not hydrochloric as the Manganate (VII) oxodises the Cl- ion instead!
Mn(7+) is reduced to Mn(2+) going from purple to colourless/pale pink. The Fe(2+) ions are oxidised to Fe(3+) ions to complete the redox reaction.
