Khemical Sulfuric Acid 14B 15% - Technical Grade - 55 Gallon (4/Plt)
About this product
Khemical Sulfuric Acid 14B 15% is a technical-grade dilute aqueous sulfuric acid solution, supplied in 55-gallon drums. The designation 14B refers to a concentration of approximately 14 degrees Baume, corresponding to approximately 15% sulfuric acid (H2SO4) by weight. It is a strong mineral acid used for water acidification and pH reduction and is corrosive.
Definition
The Baume (Be) scale is a hydrometer-based density scale used to express the concentration of acid solutions; for liquids denser than water, a higher Baume reading corresponds to a higher specific gravity and concentration.
Chemical Composition and Properties
| Property | Value |
|---|---|
| Chemical name | Sulfuric acid (aqueous solution) |
| Formula | H2SO4 |
| CAS No. | 7664-93-9 |
| Concentration | Approximately 15% by weight (14 degrees Baume) |
| Molar mass (H2SO4) | 98.08 g/mol |
| Grade | Technical |
| Appearance | Clear, colorless to slightly yellow liquid |
| Solubility | Miscible with water (exothermic on mixing) |
| Hazard class | 8, Corrosive |
Functional Mechanism
Dissociates in water to hydrogen and sulfate ions, lowering pH and neutralizing carbonate and bicarbonate alkalinity in irrigation and process water to a target set point, which also helps prevent mineral scale in lines and emitters.
Target Applications
- Acidification of irrigation and fertigation water and pH reduction.
- 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; mixing is strongly exothermic.
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. 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.
Safety and First Aid
- Causes severe skin burns and serious eye damage (H314).
- Eye contact: rinse with water for 15 to 20 minutes, removing contact lenses after the first 5 minutes; seek immediate medical attention.
- Skin contact: remove contaminated clothing; rinse for 15 to 20 minutes.
- Inhalation: move to fresh air; seek medical attention.
- Ingestion: 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; use media appropriate to the surrounding fire. Sulfur oxides may be generated during a fire.
Environmental Precautions
Harmful pH shift in water; prevent uncontrolled discharge to soil or waterways.
Compliance
Sulfuric acid carries a CERCLA/SARA reportable quantity of 1,000 lb. IARC classifies industrial exposure to strong inorganic-acid mists containing sulfuric acid as carcinogenic to humans; prevent mist inhalation through engineering controls and respiratory protection.
