Hydrochloric Acid, 37% is an excellent acidifying reagent. It is a colourless 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. The fact that it is available as a pure reagent make it an excellent acidifying reagent. 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.
