It is a clear, colorless liquid with a pungent, irritating odor, supplied at a nominal 5% w\/w concentration so that operations receive a ready-to-use strength without diluting concentrated acid on site.\u003c\/p\u003e\u003cp\u003eBecause the solution is made from ACS Reagent Grade feedstock and deionized water, it carries the low trace-impurity profile of the ACS article rather than the wider tolerances of a technical grade — the practical difference between the two grades is impurity content, not strength.\u003c\/p\u003e\u003ch3\u003eWhy This Grade\u003c\/h3\u003e\u003cp\u003eThe ACS \u003cem\u003eReagent Chemicals\u003c\/em\u003e monograph for hydrochloric acid specifies an assay of 36.5–38.0% together with the trace-impurity ceilings below.
