Morphology
The phrase is compositionally an adjective + noun (an acid that is perchloric), so the basic idea 'a type of acid' is derivable from the constituents. However, 'perchloric' is a technical, specialised chemical term and the specific properties (very strong, highly corrosive, powerful oxidizer) are not predictable from general knowledge of the words by a B1 learner without domain knowledge. Therefore the structure is partly transparent but requires specialised knowledge to recover the full meaning.
Etymology
Perchloric acid gets its name from the prefix per- meaning 'more' and chloric meaning 'from chlorine'. Think of a family of chlorine acids: the one with the most oxygen was called perchloric, and that name points to the fact it is a very strong, dangerous acid today.
