Product Overview
pH-Ree Fall is a highly stable buffering solution formulated from phosphoric acid (CAS 7664-38-2), designed to deliver exceptional pH control and stability across various industrial processes. Phosphoric acid, represented by the chemical formula H3O4P with a molecular weight of 97.995, is an odorless, dense liquid that sinks in water due to its high relative density. Industries rely on this mineral acid to establish and maintain precise acidic environments, preventing rapid fluctuations in pH that can compromise chemical reactions, compromise product quality, or damage sensitive equipment. As a premier buffering agent, it acts by providing a reservoir of hydrogen ions to neutralize alkaline shifts.
Our pH-Ree Fall buffering solution is shipped as a clear, colorless liquid, offering outstanding miscibility with water and other aqueous media. The product's high density (1.892 at 77 °F) and low vapor pressure (0.03 mmHg) make it an efficient and stable chemical component in closed-loop systems, waste treatment facilities, and manufacturing lines. Utilizing this phosphoric acid solution ensures a controlled reaction environment, which is highly beneficial for operations involving metal finishing, fertilizer manufacturing, and textile processing where process parameters must be maintained within narrow operational windows.
Why This Grade
Selecting the correct concentration and formulation of phosphoric acid is critical to ensuring consistent buffering performance and avoiding costly system failures in systems utilizing industrial acids. Industrial processes require a specific grade tolerance to maintain precise equilibrium; using an unverified or inconsistent grade can lead to rapid pH drifts, which can ruin batches of chemical mixtures, degrade process equipment, or cause uncontrolled precipitation in aqueous systems. In industrial water treatment or metal pretreatment lines, a precise buffering capability is necessary to ensure that chemical reactions proceed at optimal rates without risking the corrosion of structural components.
A secondary risk of using incorrect grades of phosphoric acid is the introduction of unwanted impurities, which can poison catalysts, interfere with surface finishes in anodizing baths, or lead to regulatory non-compliance in effluent discharge. By utilizing Alliance Chemical's pH-Ree Fall, facilities avoid these failure modes, ensuring that the concentration of the acid is optimized for long-term pH stability without unwanted secondary reactions. This controlled formulation provides a reliable and steady response to alkaline contamination, offering a predictable buffering capacity that matches the demanding standards of modern chemical distribution.

Hazmat & Shipping
Because pH-Ree Fall is a concentrated phosphoric acid solution, it is classified as a regulated hazardous material for transport. It is officially designated as UN1805, PHOSPHORIC ACID SOLUTION, under Hazard Class 8 (Corrosive substances), with Packing Group III. The GHS signal word for this chemical is Danger, reflecting its potential to cause severe skin burns and eye damage as indicated by the GHS hazard statement H314. No GHS pictograms are associated with this product as per the authoritative registry block, but its corrosive nature to metals and living tissue demands rigorous adherence to Department of Transportation (DOT) shipping protocols.
Safe transportation of this material requires specialized packaging that can withstand the corrosive properties of the mineral acid. During transport and handling, personnel must utilize appropriate personal protective equipment (PPE) to mitigate the risks associated with the H314 hazard code; this includes chemical-resistant gloves, protective clothing, eye protection, and face protection. Alliance Chemical coordinates all logistics in strict compliance with federal regulations, ensuring that every shipment is delivered safely and securely via qualified hazmat carriers to prevent accidental release or exposure in transit.
Handling & Storage
Proper storage of pH-Ree Fall requires storing the liquid in a cool, dry, well-ventilated area, ideally within a temperature-controlled environment above its freezing point of 108 °F (when pure) or standard solution freezing ranges to prevent crystallization. Compatible container materials include high-density polyethylene (HDPE), polypropylene, or glass, as this corrosive acid will attack many metals, including carbon steel and aluminum. Keep containers tightly closed when not in use, and store away from incompatible materials such as strong bases, strong oxidizing agents, and active metals that can generate flammable hydrogen gas.
