A chemical compound containing gold, sulfur, and oxygen atoms, often used in gold extraction and medical treatments.
From Latin 'aureus' (golden) + 'thio-' (combining form for sulfur) + 'sulphate' (salt of sulfuric acid). This chemistry term was created in the 19th century when scientists began systematically naming compounds with gold.
Aurothiosulphate has been used in medicine to treat arthritis and was once injected directly into patients—one of gold's surprising medical uses before modern pharmaceuticals took over!
