Hydrochloric Acid, 6.0 N, Aqueous Solution, APHA, is a colorless and clear, highly corrosive, highly pungent solution of hydrogen chloride in water. As an monoprotic acid and one of the six common strong mineral acids it is the least likely to be subject to an oxidation-reduction reaction. Hydrochloric acid is also frequently used during chemical analysis to prepare samples for analysis. It reacts with basic compounds, turning them into dissolved chlorides that can then undergo analysis.
