Definition
- Adjective:
- Relating to or containing tin, especially in its tetravalent state (Sn⁴⁺): "Stannic" is a chemical term used to describe compounds in which tin has a valence of four. It is the higher of the two common oxidation states for tin.
Usage
- The word "stannic" is used almost exclusively in chemistry and related scientific fields. It specifies the oxidation state of tin within a compound. It is typically used attributively before a noun (e.g., stannic chloride).
Examples
- Adjective:
- Stannic oxide (SnO₂) is a common compound used in ceramics.
- The laboratory procedure required the use of stannic chloride as a catalyst.
Advanced Usage
- "Stannic" vs. "Stannous": These terms distinguish between the two main oxidation states of tin. "Stannic" refers to tin(IV) or Sn⁴⁺, while "stannous" refers to tin(II) or Sn²⁺.
- Ferric and ferrous are to iron as stannic and stannous are to tin.
Variants and Related Words
- Stannous (adj): Of or containing tin, especially in its divalent state (Sn²⁺).
- Stannous fluoride is an ingredient in some toothpastes.
Synonyms
- Tin(IV): The systematic modern chemical nomenclature for the Sn⁴⁺ cation or its compounds.
- Tin(IV) oxide is synonymous with stannic oxide.
Adjective
- of or relating to or containing tin
