Morphology
The phrase is compositionally interpretable: a learner who knows 'microcosmic' (small-scale/representative) and 'salt' (an ionic compound) will infer it denotes a particular kind of salt. However, the precise chemical identity, crystalline form and analytical use (sodium ammonium hydrogen phosphate found in urine) are specialized facts that cannot be derived from the constituents, so the meaning is only partially predictable.
Etymology
Microcosmic salt comes from old chemists who made this white salt from urine and called it microcosmic because they thought the body was a tiny world, a 'microcosm'. That's why the name stuck, and today microcosmic salt means the white lab salt used to test for metal oxides.
