History

Etymology

From French sulfate, from New Latin sulphatum, taken from the expression acidum sulphatum (“sulfuric acid”), from sulphatus, from Latin sulphur (“sulfur”). The term was first used in 1787 by the French chemist L. B. G. De Morveau. Equivalent to sulf(ur) + -ate (“salt or ester”).

From the above noun, through -ate (verb-forming suffix).
