Is potassium manganate and potassium permanganate the same?
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.
What is the chemical reaction of Potassium permanganate?
"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
What compounds is the strongest oxidising agent MnO2 K3MnO4 K2MnO4 KMnO4?
Among the compounds listed, potassium permanganate (KMnO4) is the strongest oxidizing agent. It can readily donate oxygen atoms in reaction with other substances, making it a powerful oxidizing agent in various chemical processes.
What is the reaction between alkene and bayer reagent?
well this reaction its a test for distinction of unsaturated hydrocarbons from saturated ones.and when unsaturated hydrocarbons react with baeyer's reagent its pink colour disappears. What happens in this reaction is actually the KMnO4 reacts with alkali and releases K2MnO4+H2O+[O] The nascent oxygen along with water reacts with alkene giving off alkanediol.
Empirical formula for potassium manganate?
The empirical formula for potassium manganate is KMnO4.

What is the word equation for potassium permanganate when heated?
here is the rection... 2KMnO4 + 3H2SO4 = K2SO4 + 2MnSO4 + 3H2O + 2.5O2 (alkaline) and in other conditions... 6 KMnO4 + 9 H2SO4 → 6 MnSO4 + 3 K2SO4 + 9 H2O + 5 O3 The H2SO4/KMnO4 reaction can also produce the oily Mn2O7, which is unstable and can decompose explosively.
What is the role of KOH in the preparation of potassium manganate?
KOH is the reactant in this reaction:2 MnO2 + 4 KOH + O2 = 2 K2MnO4 + 2 H2O
What is the compound name for K2MnO4?
The compound name for K2MnO4 is potassium permanganate.
What happens when you heat potassium permanganate?
I'm not entirely sure but I'm pretty positive it turns black, thus releasing oxygen and this can be proved if the test tube containing the potassium manganate VII is connected to another test tube or bowl containig limewater because it will start to bubble and turn cloudy or milky.
Is potassium maganate VII an oxidising agent?
Yes, potassium permanganate (KMnO4) is a strong oxidizing agent. It can undergo reduction and in the process oxidize other substances, making it useful in various chemical reactions, water treatment, and laboratory applications.
What is the chemical equation for the reaction between methanoic acid and acidified potassium permanganate?
The chemical equation for the reaction between methanoic acid (HCOOH) and acidified potassium permanganate (KMnO4) is: 2KMnO4 + 5HCOOH + 3H2SO4 → 2MnSO4 + K2SO4 + 5CO2 + 8H2O This reaction is a redox reaction where potassium permanganate is reduced from +7 to +2 oxidation state and methanoic acid is oxidized to carbon dioxide.
What is potassium permanganate?
Potassium permanganate is a chemical compound used for a variety of purposes, such as water treatment, medicinal applications, and as a disinfectant. It appears as dark purple crystals or powder and is known for its strong oxidizing properties.
What is oxidation number for Me in K2Mno4 -1?
In K2MnO4, the oxidation state of oxygen is -2, and the overall charge of the compound is -1. Given that potassium has a +1 oxidation state, the oxidation state of manganese (Mn) in this compound is +7.
What gas does Potassium permanganate give off when it is cracked and turned black?
Oxygen gas in evolved. 2KMnO4 ---> K2MnO4 + MnO2(s) + O2
