Morphology

acidic + hydrogen

The noun phrase is directly compositional: 'acidic' (having acid properties) modifies 'hydrogen' (the element), so it straightforwardly denotes hydrogen that is acidic or associated with acids. While full understanding of proton donation is technical, the basic sense 'hydrogen related to/accompanying acids' is predictable from the constituents for a B1 learner.

Etymology

Acidic hydrogen gives a clear picture: a hydrogen atom in an acid that is ready to leave. When that hydrogen leaves as a small positive particle called a 'proton', the acid becomes acidic, so the phrase means a hydrogen that can be 'released' as a positive ion.
