Reagent H2SO4 Sulfuric Acid 60 Percent High Purity Industrial Grade Chemical Solution

Reagent Sulfuric Acid 60% is a high-purity acid solution (typically meeting ACS specifications) that offers a practical balance between strong acidity and safe handling. With reduced fuming, lower viscosity, and a lower heat of dilution than 96–98% grades, it serves as a versatile stock acid for preparing more dilute solutions, carrying out analytical digestions, and performing moderately strong acid-catalyzed reactions without the extreme aggressiveness of concentrated acid.

• Convenient Stock Acid: Easily diluted to prepare 1 M to 4 M sulfuric acid solutions with significantly less heat and spattering than 98% acid.

• Wet Digestion and Ashing: Used in the digestion of organic samples for Kjeldahl nitrogen determination, COD (Chemical Oxygen Demand), and heavy metal analysis where a controlled, moderate acid strength is required.

• pH Adjustment and Sample Preservation: Acidifies water, wastewater, and extracts for nutrient and metal analysis; the 60% concentration is easier to handle accurately than fuming grades.

• Colorimetric and Spectrophotometric Methods: Provides the acidic medium for silica, phosphate, and other color-development reactions where a consistent 1–2 M acid concentration is needed.

• Mild Sulfonation and Nitration: Provides the acid strength necessary for some sulfonation and nitration reactions while limiting over‑nitration or charring that can occur with 98% acid.

• Hydrolysis of Esters and Amides: Catalyzes hydrolysis under controlled conditions, useful for intermediate synthesis in pharmaceutical and agrochemicals.

• Condensation Reactions: Serves as the catalyst in Knoevenagel, Pechmann, and aldol condensations where a relatively strong acid is needed but concentrated acid would cause side reactions.

• Deprotection and Cleavage: Applied in peptide synthesis and carbohydrate chemistry for removing acid‑labile protecting groups that require a moderately strong acid environment.

• Resin Regeneration: Conveniently diluted to 5–10% for regenerating cation exchange resins in laboratory and industrial water demineralizers, providing high purity and low metal contamination.

• TOC/TIC Analysis: Used in total organic carbon analyzers that require a defined sulfuric acid concentration for inorganic carbon removal.

• Soil and Sediment Extraction: Employed in certain soil nutrient extraction methods where dilute acid is prepared from a reliable 60% stock.

• Lead-Acid Battery Electrolyte Preparation: Can be used as a stock acid for blending battery electrolyte (specific gravity 1.22–1.28, ~33–37% H₂SO₄) by dilution with distilled water. Though 70% is more common, 60% still allows accurate mixing with manageable heat evolution.

• Battery Manufacturing and Maintenance: Serves as a high-purity acid source for electrolyte top‑up and adjustment in service centers, ensuring trace-metal-controlled quality.

• Metal Surface Pickling: Applied in diluted form to clean copper, brass, and mild steel surfaces, removing oxides and scale before plating or coating without the hazardous fumes of concentrated acid.

• Specialty Sulfate Production: Starting material for the preparation of reagent‑grade metal sulfates used in analytical standards and pharmaceutical excipients.

• pH Control in Process Water: Utilized in cooling towers, dyeing, and textile processing where a ready-to-use moderate acid is needed.
