The chemical name "Chenique Acid" is a bit tricky in terms of spelling. It is pronounced as /ʃeɪˈniːk/ acid, with the "Ch" making a "sh" sound, "e" as in "hey", "i" as in "bee", and the last syllable is stressed. The correct spelling is "Chenique" with a "Ch" and not "Sheenique" with a "Sh". This acid is commonly used as a reducing agent in the production of dyes and pharmaceuticals.
