FAQs
What is the concentration and chemical identity of this product?
This product is concentrated phosphoric acid (H₃PO₄) at 85 % by weight, supplied in a 1-gallon container. It is a clear, water-white to slightly viscous liquid.
What hazards are associated with 85% phosphoric acid, and how should it be handled?
85% phosphoric acid is corrosive: it can cause severe skin burns, eye damage, and corrosion of metals. Protective gloves, goggles or face shield, and acid-resistant clothing are mandatory. Work in a well-ventilated area and avoid inhalation of vapors or mists.
What materials are suitable for the storage of concentrated phosphoric acid?
Use acid-resistant containers such as high-density polyethylene (HDPE), polypropylene (PP), or appropriately lined metal (e.g., low-corrosion stainless steel) for 85% phosphoric acid. Avoid reactive metals like aluminum, iron, or zinc that may corrode or generate hydrogen gas.
What should be considered when storing this acid?
Store in a cool, dry, well-ventilated area, away from incompatible materials (strong bases, oxidizers, reactive metals). Keep the container tightly closed when not in use. Ensure storage areas have spill containment and access to eyewash/shower equipment.
What precautions apply for accidental spills or disposal?
In case of spill, contain and absorb with inert, non-combustible absorbent. Neutralize remnants carefully (e.g., with sodium bicarbonate), then rinse thoroughly. Dispose of waste according to local hazardous-waste regulations. Do not release into drains without neutralization.
