The equivalent mass of K2MnO4 is calculated by dividing the molar mass by the change in oxidation state of the element being reduced or oxidized. For K2MnO4, the molar mass is 198.1 g/mol. Since the Mn in MnO4^- has an oxidation state of +7 in the permanganate ion and is reduced to +2 in Mn^2+, the change in oxidation state is 5. Therefore, the equivalent mass of K2MnO4 is 198.1 g/mol / 5 = 39.62 g/equiv.

What is the compound name for K2MnO4?
The compound name for K2MnO4 is potassium permanganate.
WHAT IS THE MEDIUM FOR CONVERTING KMnO4 TO K2MnO4?
In order to convert KMnO4 to K2MnO4, a reducing agent is typically needed. One common method involves using a reducing agent like a metal, such as zinc or iron, to react with KMnO4 in an acidic medium to produce K2MnO4.
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 is equivalent mass of sulfuric acid?
The equivalent mass of sulfuric acid (H2SO4) is calculated as its molar mass divided by the number of replaceable hydrogen ions it can donate. Since sulfuric acid can donate 2 hydrogen ions (H+), the equivalent mass is half of the molar mass. Therefore, the equivalent mass of sulfuric acid is approximately 49 g/mol.
Will K2MNO4 get oxidized by ozone?
Yes, potassium permanganate (K2MnO4) is a strong oxidizing agent and can be further oxidized by ozone under certain conditions, resulting in the reduction of ozone to oxygen and the formation of manganese dioxide (MnO2).
In manufacture of potassium permanganate by electrolysis of k2mno4 what should be the equivalent weight of kmno4 how much kmno4 will be produced by 96478 coulombs or one farady?
The equivalent weight of K2MnO4 is 158 g/mol. To calculate the produced KmnO4, we first determine the number of faradays in 96478 coulombs (1 F = 96485 C). Then we use the stoichiometry: 1 mol of K2MnO4 produces 1 mol of KMnO4. So, 158 g of K2MnO4 will produce 158 g of KMnO4.

If subatomic particle with a mass equivalent to a proton is what?
The neutron has a mass very close to the mass of proton (but not identical).
What is the equivalent mass of hydrochloric acid?
36.5
Definition of equivalent mass?
Equivalent mass is a concept used in chemistry to calculate the mass of a substance that can react or combine with one mole of hydrogen ions or exchangeable ions. It is often used in acid-base and redox reactions to determine the equivalent weight of a substance.
