What does manganic mean?
Manganic is a chemistry adjective relating to manganese, particularly compounds in which manganese has the +3 oxidation state. Its best-known use is in the name “manganic oxide,” the traditional designation for manganese(III) oxide. The term also appears in names such as “manganic acid” and in references to manganic salts. It should not be confused with “manganous,” which describes manganese in the more familiar +2 oxidation state, or with “manganese,” which names the element itself. In modern technical writing, a specific oxidation-state description—such as “manganese(III) oxide”—may be clearer than the traditional adjective. Manganic is therefore most useful to readers encountering older chemistry texts, systematic compound names, or discussions that explicitly contrast the +2 and +3 states of the element.
adjectiveOf or relating to manganese, especially to compounds in which manganese has the +3 oxidation state.
- Relating to manganese, especially to compounds containing manganese in the +3 oxidation state.
"Manganic oxide is the traditional name for manganese(III) oxide."
"The compound was historically described as manganic oxide, though manganese(III) oxide is now preferred."
"Manganic salts were once used in laboratory demonstrations involving oxidation and reduction."
Manganic flags manganese’s less familiar +3 state, a setting that invites confusion with the more familiar +2 state.

Etymology of manganic
Manganic was formed within the scientific vocabulary of chemistry from manganese and the adjective-forming suffix -ic. It belongs to a family of related chemical terms that distinguish different oxidation states and compounds of manganese, including manganous, manganate, and manganite. These words share the manganese element through the chemical terminology ultimately associated with Latin and earlier European mineral names for manganese-bearing substances.
How manganic is actually used
A technical chemistry term used mainly in formal scientific and historical contexts. It is chiefly encountered in compound names such as “manganic oxide” and “manganic acid”; modern chemical nomenclature often specifies the oxidation state directly instead.
Easily confused with manganic
Manganic refers to manganese in the +3 oxidation state, whereas manganous refers to manganese in the +2 state.
