British spelling relating to acids or compounds containing two sulfur atoms.
British variant of disulfuric, from dis- + sulph- + -uric, where -uric relates to 'urine' in earlier chemistry (as sulfuric was thought to relate to burning), both now etymologically obscure.
The 'uric' in sulfuric doesn't actually come from urine despite what it sounds like—it comes from obsolete Latin terminology meaning 'of or from burning,' making the word a linguistic fossil.
