MnO2: oxidation number +4
KMnO4: oxidation number +7
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.
In potassium permanganate (KMnO4), the manganese (Mn) atom is in the +7 oxidation state, leading to its electron configuration of [Ar] 3d^0 4s^0. Since there are no electrons in the 3d or 4s orbitals, there are no unpaired electrons in KMnO4. Therefore, KMnO4 has zero unpaired electrons.
Potassium Hydroxide is KOH and potassium permanganate is KMnO4.
its MnO4 that gives purple colour to the KMnO4 solution. MnO4 absorbs all the six colours present in the white light except for indigo and this colour reflects back to our eyes that is why we see it as purple coloured solution.

Manganese oxidation state = +7 So, it is also called Manganate(VII)
MnCl2: oxidation number +2MnO2: oxidation number +4KMnO4: oxidation number +7
The oxidation state of the manganese atom in the compound KMnO4 is 7.
The oxidation number of manganese in MnO4 1- is +7. Each oxygen atom has an oxidation number of -2, and the overall charge of the ion is -1. Therefore, the oxidation number of manganese can be calculated as +7 to balance the charges.
The oxidation number for oxygen in KMnO4 is -2. The total oxidation number for the compound must equal zero (since it is neutral), and since the oxidation number for potassium (K) is +1 and for manganese (Mn) is +7, the oxidation number for oxygen must be -2 to balance the charges.
The oxidation number of manganese (Mn) can vary depending on the compound it is in. In MnO2, the oxidation number of Mn is +4, while in KMnO4, the oxidation number of Mn is +7.
The oxidation number of Mn in KMnO4 is +7. This can be determined by assigning the known oxidation numbers of potassium (+1) and oxygen (-2) and solving for the unknown oxidation number of manganese.
The oxidation number of manganese in KMnO₄ is +7. Manganese has an oxidation number of +7 in this compound because oxygen has an oxidation number of -2, and the overall charge of the permanganate ion is -1, so the sum of the oxidation numbers must equal -1.
K has an oxidation number of +1 O has an oxidation number of (-2) x 4 So... the oxidation number for Mn is whatever is needed to make 1-8 equal to zero. Therefore, the oxidation number for Mn is +7
The oxidation number of manganese depends on the particular compound in which manganese is present. The most common oxidation states are +2 as in MnCl2, + 4 as in MnO2, and + 7 as in potassium permanganate, KMnO4.
The maximum oxidation number is the highest possible oxidation state that an element can exhibit in a chemical compound. It is typically reached when the element gains or loses electrons to achieve a stable configuration.
K has an oxidation number of +1 O has an oxidation number of (-2) x 4 So... the oxidation number for Mn is whatever is needed to make 1-8 equal to zero. Therefore, the oxidation number for Mn is +7
