    The fixer is sodium thiosulphate (Na2S2O3), historically nicknamed 'hypo'; 'sodium hyposulphite' is the dated misnomer

    What the page claimed

    It was the discovery of sodium hyposulphite (hypo) as a fixer by John Herschel in 1839 that completed the essential chemistry.

    What was corrected

    It was the discovery of sodium thiosulphate (hypo) as a fixer by John Herschel in 1839 that completed the essential chemistry. Verified body text (only one mention) is already correctly fixed, and the FAQ contains no mention of the fixer chemical name.

    Why: Already correct everywhere: the body text correctly uses 'sodium thiosulphate' rather than the dated misnomer 'sodium hyposulphite', with no stray mentions elsewhere. No changes were required.
