Morphology

bisulfate = sulfate (semi-transparent) = bis + sulfate

Formed by prefixing 'bis-' to 'sulfate' following chemical naming conventions, but the precise chemical implication of 'bis-' is not predictable from everyday 'bi-/bis-' meaning 'two' for most learners.

Etymology

The word bisulfate combines the prefix bi- and sulfate, and sulfate means 'a salt of sulfur'. In older chemical names bi- was used to mean 'one hydrogen', as in bicarbonate, so bisulfate is a sulfate that still has one hydrogen (HSO4−), which explains its modern meaning.
