Morphology
The term is compositionally built from 'sodium' (the element) and 'hydroxide' (the hydroxyl-based base), so its meaning as the hydroxide of sodium (NaOH) is directly derivable from the parts. Although technical, this chemical-naming pattern is regular and cross-linguistically recognizable, so a learner who knows both constituents can infer the MWE's meaning.
Etymology
Sodium hydroxide gets its name from its two parts: sodium, a soft metal, and hydroxide, a group linked to water, so the name literally says what it is made from. That's why this white, very strong chemical is also called 'caustic soda' and can burn the skin or be used to make soap and paper.
