Muriatic, or hydrochloric, acid -- a concentrated water solution of hydrogen chloride -- can adjust the pH of basic solutions. Muriatic acid uses include the purification of common salt; household cleaning; leather processing; and as a component in the production of organic compounds. The range of concentration of muriatic acid lies between 36.5 percent and 38.0 percent, with a density of 1.189 g per ml. Concentrated muriatic acid contains 1 g of pure muriatic acid per approximately 2.25 ml.
