Ortho Acid FAQ
What is the difference between Ortho Acid and Phosphoric Acid?
Ortho Acid (H3PO3) and phosphoric acid (H3PO4) are distinct compounds with different chemical structures and properties. Ortho Acid has three hydrogen atoms and one less oxygen atom compared to phosphoric acid. This structural difference makes Ortho Acid a stronger reducing agent, while phosphoric acid is more commonly used as an acidulant and pH adjuster.
How should Ortho Acid be stored for optimal shelf life?
Ortho Acid should be stored in tightly sealed containers made of polyethylene or other acid-resistant materials. The storage area must be cool (below 30°C), dry, and well-ventilated, away from alkaline substances, oxidizing agents, and moisture. Under proper conditions, Ortho Acid maintains stability for at least 24 months from production date.
What safety precautions are necessary when handling Ortho Acid?
When handling Ortho Acid, always wear chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas or use local exhaust ventilation. Avoid skin contact and inhalation of dust. In case of contact, immediately flush affected areas with plenty of water for at least 15 minutes. For eye exposure, rinse continuously with water and seek medical attention.
