Khemical Sulfuric Acid 10% - 55 Gallon (4/Plt)
About this product
Khemical Sulfuric Acid 10% is a dilute aqueous sulfuric acid solution (10% H2SO4 by weight, balance water), supplied in 55-gallon drums (4 per pallet). It is a strong mineral acid used for irrigation-water and process-water acidification and pH reduction. The solution is corrosive and dissociates fully in water to release hydrogen ions.
Chemical Composition and Properties
| Property | Value |
|---|---|
| Chemical name | Sulfuric acid (aqueous solution) |
| Formula | H2SO4 |
| CAS No. | 7664-93-9 |
| Concentration | 10% by weight |
| Molar mass (H2SO4) | 98.08 g/mol |
| Appearance | Clear, colorless to slightly yellow liquid |
| Odor | Odorless |
| Solubility | Miscible with water (exothermic on mixing) |
| Hazard class | 8, Corrosive |
Functional Mechanism
Sulfuric acid dissociates in water to hydrogen and sulfate ions, lowering pH. In irrigation and process water it neutralizes carbonate and bicarbonate alkalinity, reducing pH to a target set point and helping prevent mineral scale formation in lines and emitters.
Target Applications
- Acidification of irrigation and fertigation water and pH reduction to a target set point.
- Neutralization of bicarbonate alkalinity.
- Descaling and maintenance of irrigation lines and water-handling equipment.
Application Specifications
Meter into the water stream to the target pH using acid-compatible injection equipment. When diluting, always add acid slowly to water, never water to acid, because mixing is strongly exothermic and adding water to acid can cause violent spattering.
Use Restrictions and Compatibility
Reacts violently with water on direct addition. Incompatible with metals (generates flammable hydrogen gas), strong bases, organic materials, strong reducing agents, and strong oxidizers. Corrosive to aluminum alloys; conventional 300-series austenitic stainless steels show better resistance in very dilute or highly concentrated acid than at intermediate concentrations. Use acid-resistant materials for storage and transfer.
Storage and Handling
Store in a cool, well-ventilated area within acid-resistant secondary containment, away from metals, bases, organics, and oxidizers. Wear chemical-resistant gloves (neoprene or PVC), chemical splash goggles or face shield, and protective clothing; use an acid-gas respirator where exposure limits may be exceeded.
Safety and First Aid
- Causes severe skin burns and serious eye damage (H314). May cause burns to the gastrointestinal tract if swallowed.
- Eye contact: rinse with plenty of water for 15 to 20 minutes, removing contact lenses after the first 5 minutes; seek immediate medical attention.
- Skin contact: remove contaminated clothing; rinse skin with water for 15 to 20 minutes.
- Inhalation: move to fresh air; seek medical attention.
- Ingestion: have the conscious person sip water; do not induce vomiting; do not attempt to neutralize; seek immediate medical attention.
Firefighting Measures
Non-combustible. Do not apply water directly to concentrated acid, which can generate heat and spattering; use extinguishing media appropriate to the surrounding fire. Irritating or toxic sulfur oxides may be generated during a fire.
Environmental Precautions
Harmful pH shift in water; endangers water supplies if released to soil or waterways. Prevent uncontrolled discharge.
Compliance
Sulfuric acid carries a CERCLA/SARA reportable quantity of 1,000 lb. Industrial exposure to strong inorganic-acid mists containing sulfuric acid is classified by IARC as carcinogenic to humans; engineering controls and respiratory protection should prevent mist inhalation.
