manganate

Thân thiện

A student prepares a solution of potassium manganate in the laboratory.

Definition

Noun: * A salt of manganic acid containing manganese as its anion: A chemical compound where the negatively charged ion (anion) is derived from manganic acid (H₂MnO₄), containing manganese in a +6 oxidation state.

Usage

• As a chemical compound: The term is used primarily in chemistry to describe specific ionic compounds containing the MnO₄²⁻ anion.
  • Potassium manganate (K₂MnO₄) is a green-colored salt.
  • The synthesis of sodium manganate was described in the experiment.

Advanced Usage

• In redox chemistry: Manganate ions are often intermediates in reactions involving permanganate (MnO₄⁻) and manganese dioxide (MnO₂).
  • In alkaline solution, permanganate can be reduced to green manganate.

Variants and Related Words

• Permanganate (noun): A salt containing the MnO₄⁻ anion, where manganese is in a +7 oxidation state (e.g., potassium permanganate, KMnO₄).
• Manganic (adjective): Relating to manganese in a +3 or +6 oxidation state (e.g., manganic acid, H₂MnO₄).

Synonyms

• Manganate salt: A more descriptive synonym.
• Mn(VI) compound: A notation specifying the +6 oxidation state of manganese.

Notes on Different Meanings

• The term manganate has a very specific meaning in inorganic chemistry and is not used in general language. It should not be confused with the more common permanganate.
