It is a clear, fuming, strongly corrosive acid used where high acid strength is needed but full 37% concentration is not required.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat 32% w\/w means.\u003c\/strong\u003e The concentration is by weight: every 100 g of solution contains 32 g of hydrogen chloride. With a density of about 1.16 g\/cm³, that equals roughly 371 g of HCl per liter, or about 10.2 M (calculated).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlso known as muriatic acid.\u003c\/strong\u003e Hydrochloric acid has long been sold as muriatic acid, especially at industrial strengths of 30 to 32%. Whatever the name, it is the same chemical: hydrogen chloride dissolved in water.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA strong, complete acid.\u003c\/strong\u003e HCl dissociates completely in water, which makes it one of the most powerful common acids for dissolving metal oxides, carbonates, and scale. It reacts with carbonate deposits to release carbon dioxide and with many metals to release hydrogen gas.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhy 32%.\u003c\/strong\u003e A 32% solution fogs less than 37% acid and is a common technical- and industrial-strength option, while still delivering high reactivity for cleaning, pickling, and pH control. It is a practical choice for applications that do not need ACS reagent purity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiluting safely.\u003c\/strong\u003e To prepare working solutions, add the acid slowly to water with stirring in a fume hood; never add water to acid, and let the mixture cool. A 1+1 dilution by volume gives roughly 5 M acid (calculated).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandling at a glance.\u003c\/strong\u003e Open 32% hydrochloric acid only in a fume hood, since it releases hydrogen chloride fumes. Wear chemical splash goggles, a face shield, and acid-resistant gloves, and store containers in a ventilated corrosives cabinet with secondary containment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade and purity.\u003c\/strong\u003e This 32% acid is suited to cleaning, pickling, pH control, and general preparation work. For trace-metal analysis or standard preparation, ACS reagent 37% hydrochloric acid with defined impurity limits is the better choice.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhere it is used.\u003c\/strong\u003e Laboratories and production areas use 32% hydrochloric acid for metal pickling and oxide removal, descaling equipment, etching, pH adjustment of process water and effluent, regenerating ion exchange resins, and preparing diluted acid solutions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003ctable style=\"width:100%;
