The correct spelling of the word "Hydrofluate" is actually "Hydrofluoride." The confusion may come from the similarity between the chemical elements Fluorine and Fluoride. In IPA phonetic transcription, the correct pronunciation is [ˌhaɪ.drə.ˈfluə.raɪd]. The word is composed of two parts: "Hydro," indicating the presence of hydrogen in the compound, and "Fluoride," indicating the presence of fluoride ions. Hydrofluorides are commonly used in industrial applications and in the manufacturing of certain chemicals.
A compound of hydrofluoric acid with a base.
