Product Overview

Orthophosphoric Acid 85% AR is a high-purity, analytical-grade reagent designed for precision in laboratory applications. This clear, colorless liquid is widely recognized for its stability, low volatility, and strong acidic properties, making it a staple in research and analytical chemistry. The 85% concentration ensures optimal reactivity while maintaining ease of handling, and its AR-grade certification guarantees minimal impurities, ensuring accurate and reproducible results. The acid is highly soluble in water and alcohol, making it versatile for various formulations, including buffer solutions, pH adjustments, and as a reagent in chemical synthesis. Its non-oxidizing nature further enhances its utility in redox-sensitive reactions. Packaged in high-density polyethylene (HDPE) bottles, it is resistant to corrosion and leakage, ensuring safe storage and long shelf life. Whether used in titration, cleaning, or as a catalyst, this orthophosphoric acid delivers consistent performance, meeting the stringent demands of modern laboratories.

FAQs

1. What is the shelf life of Orthophosphoric Acid 85% AR?

When stored in a cool, dry place in its original tightly sealed container, Orthophosphoric Acid 85% AR has a shelf life of 24 months from the date of manufacture. Avoid exposure to moisture and direct sunlight to maintain its stability.

2. Is this acid compatible with glassware and plastic lab equipment?

Orthophosphoric Acid 85% AR is generally safe for use with borosilicate glassware and HDPE or PP plastic containers. However, prolonged contact with metals or low-grade plastics may cause corrosion or degradation. Always verify compatibility with specific materials before use.

3. Can this product be diluted for lower concentration applications?

Yes, Orthophosphoric Acid 85% AR can be diluted with deionized or distilled water to achieve lower concentrations. Always add the acid slowly to water to prevent exothermic reactions and splashing. Use appropriate personal protective equipment (PPE) during handling.

4. What safety precautions should be taken while handling this acid?

Wear chemical-resistant gloves, safety goggles, and a lab coat when handling Orthophosphoric Acid 85% AR. Work in a well-ventilated area or under a fume hood to avoid inhalation of fumes. In case of skin or eye contact, rinse immediately with plenty of water and seek medical attention.

5. Are there any alternatives to Orthophosphoric Acid for pH adjustment?

Alternatives for pH adjustment include sulfuric acid, hydrochloric acid, or acetic acid, depending on the specific application. However, orthophosphoric acid is often preferred for its buffering capacity and non-oxidizing properties, which are critical in certain chemical and biochemical processes.
