Hydrochloric/Muriatic Acid (37%) Lab Grade 99+% Purity

Hydrochloric acid, sold industrially as muriatic acid, supplied at 37 percent concentration in 500 ml, lab grade at 99+ percent purity. It is a colorless to faintly yellow fuming liquid and one of the standard strong mineral acids.

Typical work includes pH adjustment, acid digestion and titration in the laboratory, pickling and descaling of steel and other metals, etching concrete and masonry, and regeneration of ion exchange resin. It is strongly corrosive and gives off an irritating vapor, so it is used with ventilation, eye protection and acid-resistant gloves.
