Orthophosphoric acid
Product Overview & Quality
- Product Name: Orthophosphoric acid (Phosphoric acid)
- Brand: Kemaus (Product Code: KA-371)
- Grade: Analytical Reagent (AR Grade) with a premium high concentration of 85 percent. Meticulously manufactured and verified under Kemaus strict laboratory quality control standards to ensure exceptionally low trace levels of heavy metals, arsenic, chlorides, nitrates, and sulfates (at ppm thresholds). This ensures high analytical accuracy and absolute compatibility with sensitive quantitative testing protocols.
- Physical Properties: Odorless, clear, colorless, syrupy viscous liquid. It acts as a heavy-duty corrosive chemical material.
- Solubility: Completely miscible in all proportions with water and alcohol, liberating partial exothermic thermal energy upon dilution.
- Key Use: Widely utilized as a primary acid component for formulating standard phosphate buffer solutions to stabilize pH environments across biochemistry, molecular biology, and analytical laboratories. Heavily applied as a standard pH regulator to lower pH profiles in chemical processes. Commonly used as a specialized digestion reagent for breaking down mineral samples and metal compounds, and functions as a catalyst or reactant in advanced organic chemical synthesis and materials science research.
Safety & Hazards (Critical & Corrosive)
- Classification: May be corrosive to metals. Causes severe skin burns and eye damage. Harmful if swallowed.
- Health Risks: Direct tissue or ocular contact triggers immediate, intense chemical burns, painful tissue destruction, and potential permanent vision loss. Inhalation of airborne acid mists or concentrated vapors irritates the upper respiratory tract, inducing coughing, choking, or throat soreness. Ingestion causes immediate corrosive destruction to gastrointestinal membranes.
- First Aid Measures: In case of contact, immediately flush affected eyes or skin with a continuous stream of flowing water for at least 15 minutes while removing contaminated garments. Seek urgent medical emergency evaluation immediately.
Handling & Storage
- Storage: Highly Corrosive and Hygroscopic. It can absorb water vapor from open atmospheric conditions, altering its concentration baseline. Must be stored in its original, acid-resistant, tightly sealed Kemaus container inside a dedicated corrosive safety cabinet. Keep in a cool, dry, and well-ventilated storage zone at stable room temperature (below 30 degrees Celsius). Keep strictly isolated from strong bases, active metals, flammable materials, and excessive moisture.
- Precautions: Comprehensive specialized PPE is mandatory, including heavy-duty chemical-resistant gloves, splash-proof safety goggles, a full face shield, and a protective laboratory apron. Handle with caution due to its high viscosity to avoid operational splashes.
