4, also known as manganate(VI) because it contains manganese in the +6 oxidation state. [1] Manganates are the only known manganese(VI) compounds. [2] Other manganates include hypomanganate or manganate(V), MnO 3− 4, permanganate or manganate(VII), MnO − 4, and the dimanganate or dimanganate(III) Mn 2 O 6− 6. A manganate(IV) anion MnO 4−
Chemical chameleon reaction. The chemical chameleon is a redox reaction, well known from classroom demonstrations, that exploits the dramatic color changes associated with the various oxidation states of manganese.
YInMn Blue (/jɪnmɪn/; for the chemical symbols Y for yttrium, In for indium, and Mn for manganese), also known as Oregon Blue or Mas Blue, is an inorganic blue pigment that was discovered by Mas Subramanian and his (then) graduate student, Andrew Smith, at Oregon State University in 2009.
Manganese violet is the inorganic compound with the formula NH 4 MnP 2 O 7. [1] As implied by its name and composition, it is a purple, inorganic pigment. [2] Because it is often impure, the pigment's hue is varied. [3]
Barium manganate is an inorganic compound with the formula BaMnO 4. It is used as an oxidant in organic chemistry. [2] It belongs to a class of compounds known as manganates in which the manganese resides in a +6 oxidation state. Manganate should not be confused with permanganate which contains manganese(VII). Barium manganate is a powerful ...
Potassium manganate is the inorganic compound with the formula K 2 MnO 4. This green-colored salt is an intermediate in the industrial synthesis of potassium permanganate (KMnO 4), a common chemical. [1] Occasionally, potassium manganate and potassium permanganate are confused, but each compound's properties are distinct.
