Product Overview

Orthophosphoric Acid 50% AR is a high-purity, analytical-grade reagent designed for precision in laboratory applications. This clear, colorless liquid is a triprotic acid, meaning it can donate three protons in aqueous solutions, making it highly versatile for pH regulation and buffer preparation. With a concentration of 50%, it offers a balanced strength suitable for a wide range of chemical reactions without excessive dilution requirements. The AR grade ensures minimal impurities, guaranteeing reliable and reproducible results in sensitive analytical procedures. Its hygroscopic nature demands proper storage in tightly sealed containers to prevent moisture absorption, which could alter its concentration. Compatible with glass and most plastic labware, it is commonly used as a solvent, catalyst, or reactant in organic and inorganic synthesis. The acid?s strong corrosive properties necessitate careful handling with appropriate personal protective equipment (PPE), including gloves, goggles, and lab coats. Despite its corrosiveness, it is non-volatile, reducing the risk of inhalation hazards compared to other strong acids. This reagent is also valued for its role in preparing phosphate buffers, which are critical in biochemical and molecular biology protocols. Whether used for cleaning laboratory glassware or as a key component in chemical formulations, its consistency and purity make it a staple in research and industrial labs alike.

FAQs

1. What is the shelf life of Orthophosphoric Acid 50% AR when stored properly?

When stored in a cool, dry place in its original tightly sealed container, Orthophosphoric Acid 50% AR typically retains its stability for up to 2 years. Exposure to moisture or air can degrade its purity over time.

2. Can this acid be used with metal containers or piping?

No, Orthophosphoric Acid is highly corrosive to most metals, including iron, steel, and aluminum. Always use glass, HDPE, or PTFE-coated containers and piping to avoid contamination and equipment damage.

3. Is there a lower concentration alternative available for less aggressive applications?

Yes, diluted forms such as 10% or 25% Orthophosphoric Acid are available for applications requiring milder acidity. These are often used in cleaning or buffer preparation where high concentration is unnecessary.

4. How should spills of Orthophosphoric Acid 50% AR be handled?

Immediately neutralize spills with a weak base like sodium bicarbonate or lime, then absorb the residue with an inert material such as sand or vermiculite. Dispose of the waste according to local hazardous material regulations.

5. Does this product require any special disposal methods?

Yes, Orthophosphoric Acid must be disposed of as hazardous chemical waste. Neutralize it before disposal or follow institutional guidelines for acid waste management to comply with environmental safety standards.
