{"product_id":"sulfuric-acid-50-electrolyte-grade","title":"Sulfuric Acid 50% - Electrolyte Grade","description":"\u003ch2\u003eProduct Overview\u003c\/h2\u003e\u003cp\u003eSulfuric Acid 50% — Electrolyte Grade is a highly purified, mid-concentration aqueous solution designed specifically for applications requiring exact electrochemical properties. At this specific concentration, the solution provides an optimal balance of ionic conductivity and safety, minimizing the volatile reactions associated with concentrated 98% sulfuric acid. This specific grade is manufactured under stringent quality control protocols to ensure low trace metal impurities, preventing premature degradation of equipment and battery cells. As a primary mineral acid, it serves critical roles in energy storage, chemical processing, and industrial finishing.\u003c\/p\u003e\u003cp\u003eThis colorless, odorless liquid solution is highly miscible in water and exhibits high density, which requires specialized handling and dosing equipment. Alliance Chemical sources and distributes this product to meet the needs of testing laboratories, manufacturing facilities, and industrial operations across the United States. Whether utilized as an active electrolyte or a reactive chemical intermediate, our 50% sulfuric acid formulation delivers reliable performance across varied thermal ranges. We offer this material in multiple packaging configurations, from convenient individual quarts to bulk-scale industrial volumes, ensuring your operational requirements are met efficiently.\u003c\/p\u003e\u003ch3\u003eWhy This Grade\u003c\/h3\u003e\u003cp\u003eSelecting Electrolyte Grade sulfuric acid at a 50% concentration is essential for maintaining strict control over electrochemical and chemical reactions. Unlike standard industrial grades, Electrolyte Grade undergoes rigorous filtration and purification processes to eliminate iron, copper, and other metallic contaminants that can compromise battery life or ruin precise chemical processes. Using an incorrect grade with higher impurity levels results in parasitic self-discharge in battery applications, reduced charge efficiency, and accelerated grid corrosion.\u003c\/p\u003e\u003cp\u003eFurthermore, choosing a pre-diluted 50% concentration eliminates the extreme exothermic hazards associated with diluting concentrated 98% sulfuric acid on-site. The hydration reaction of concentrated sulfuric acid generates substantial heat, posing severe safety risks to operators and potential thermal stress to mixing vessels. Utilizing our pre-formulated 50% solution ensures consistency in concentration from batch to batch, protecting your systems from concentration drift and avoiding operational downtime or component failures.\u003c\/p\u003e\n\u003cdiv class=\"chemical-profile\" data-source=\"canonical\"\u003e\n\u003ch3\u003eChemical Profile\u003c\/h3\u003e\n\u003cdl\u003e\n\u003cdt\u003eCAS Number\u003c\/dt\u003e\n\u003cdd\u003e7664-93-9\u003c\/dd\u003e\n\u003cdt\u003eChemical Formula\u003c\/dt\u003e\n\u003cdd\u003eH2O4S\u003c\/dd\u003e\n\u003cdt\u003eMolecular Weight\u003c\/dt\u003e\n\u003cdd\u003e98.08 g\/mol\u003c\/dd\u003e\n\u003cdt\u003eBoiling Point\u003c\/dt\u003e\n\u003cdd\u003e554 °F at 760 mmHg (EPA, 1998)\u003c\/dd\u003e\n\u003cdt\u003eMelting Point\u003c\/dt\u003e\n\u003cdd\u003e50.65 °F (EPA, 1998)\u003c\/dd\u003e\n\u003cdt\u003eFlash Point\u003c\/dt\u003e\n\u003cdd\u003eN\/A °C\u003c\/dd\u003e\n\u003cdt\u003eSpecific Gravity\u003c\/dt\u003e\n\u003cdd\u003e1.841 (EPA, 1998) - Denser than water; will sink\u003c\/dd\u003e\n\u003cdt\u003eAppearance\u003c\/dt\u003e\n\u003cdd\u003eSulfuric acid is a colorless oily liquid.
