The spelling of "sulphovinic" can be confusing due to its use of both "ph" and "v". However, the word can be broken down phonetically as "sʌl-foh-vin-ik." The "ph" represents the sound "f," while the "v" represents a voiced "v" sound. The word is derived from "sulphuric acid" and "vinyl," and is used in chemistry to describe a certain type of derivative compound. When pronouncing "sulphovinic," be sure to use a short "u" sound as opposed to a long "oo."
A term applied to an acid produced by the action of sulphuric acid on alcohol.
