Morphology

hydrogen + carbonate

The compound name is systematically compositional: combining 'hydrogen' and 'carbonate' signals a carbonate species that includes hydrogen (i.e. the bicarbonate/HCO3− ion). Although it is technical chemistry vocabulary, the meaning is directly inferable from the constituents and follows regular scientific naming patterns found across languages, so a learner who knows both words can deduce the sense.

Etymology

Hydrogen carbonate literally names its parts: a carbonate group with one extra hydrogen, so it is also called 'bicarbonate' and is the main ingredient in 'baking soda'. So the name helps you remember it is the carbonate that has one hydrogen, which explains the word's meaning in chemistry.
