What is Manganate ion?
Manganate is a divalent inorganic anion obtained by removal of both protons from manganic acid. It is a manganese oxoanion and a divalent inorganic anion. It is a conjugate base of a hydrogen manganate.

What is the oxidation number to K in K2MnO4?
In K2MnO4 ,K is a metal having the oxidation no +1 and the oxidation no of O is -2.the compound is neutral so the sum of oxidation numbers of the elements must be 0.
How is k 2 MnO 4 synthesized in the laboratory?
In the laboratory, K 2 MnO 4 can be synthesized by heating a solution of KMnO 4 in concentrated KOH solution followed by cooling to give green crystals: This reaction illustrates the relatively rare role of hydroxide as a reducing agent.
Which is more isostructural k 2 MnO 4 or KMNO 4?
K 2 MnO 4 is a salt, consisting of K + cations and MnO 42− anions. X-ray crystallography shows that the anion is tetrahedral, with Mn-O distances of 1.66 Å, ca. 0.03 Å longer than the Mn-O distances in KMnO 4. It is isostructural with potassium sulfate.
What is the oxidation state of MN in MnO4?
Oxygen is mostly in -2 oxidation states besides peroxide, superoxides. Alkaline and alkaline-earth metals are respectively in +1 and +2 ox. states. K Mn O4 – oxidation state of Mn is “x”. So,
