Meaning and Definition
A chemical compound, specifically a salt or ester of pyrosulphuric acid.
In inorganic chemistry, any of a class of oxyanions of sulfur with the formula [S₂O₇]²⁻, or any salt containing this anion, formed by heating hydrogen sulphates. The pyrosulphate ion consists of two tetrahedral sulphate groups sharing an oxygen atom.
Dialectal Variation
British vs American Usage
Differences
Primarily a spelling difference: 'pyrosulphate' (British) vs. 'pyrosulfate' (American). The chemical ion is the same.
Connotations
None beyond the spelling variation.
Frequency
Very low frequency in both variants, limited to specialized texts. The spelling follows the general British/American pattern of 'ph'/'f' (sulphate/sulfate).

FAQ
Frequently Asked Questions
Yes, in modern IUPAC nomenclature, 'disulphate' is the preferred systematic name for the S₂O₇²⁻ ion, while 'pyrosulphate' is a traditional name still in common use.
Only in highly specialized academic or industrial chemistry contexts, such as reading a research paper on sulfate thermal chemistry, an analytical chemistry method, or a chemical inventory.
The prefix 'pyro-' (from Greek 'pyr', meaning fire) historically denoted substances obtained by heating. Pyrosulphates are typically formed by heating hydrogen sulphates.
The spelling: 'pyrosulphate' (UK) versus 'pyrosulfate' (US). The chemical meaning and usage are identical.
