early 17th century (in the sense 'sour-tasting'): from Latin acidus, from acere 'be sour'.
Acid originally meant ‘sour-tasting’ and came from Latin acidus. The term seems to have been introduced by the scientist Francis Bacon, who in 1626 described sorrel as ‘a cold and acid herb’. The chemical sense developed at the end of that century because most common acids taste sour. The acid test was originally a method of testing for gold using nitric acid. An object made of gold will show no sign of corrosion if immersed in nitric acid, unlike one made of another metal. By the late 19th century the expression had come to mean any situation that proves a person's or thing's quality. The Australian expression put the acid on, meaning ‘to extract a loan or favour from’, comes from acid test—the would-be borrower is seen as ‘testing’ their victim for resistance or weakness. Acrid (early 18th century) is from the related Latin acer ‘sharp, pungent’ with spelling influenced by acid.
