Boric Acid Extra Pure – 500 gram Packs

Boric Acid Extra Pure is an inorganic boron compound, also known as orthoboric acid, with the molecular formula H₃BO₃. It is a white crystalline solid that behaves as a weak Lewis acid in aqueous solutions and participates in borate equilibria, making it useful in a variety of laboratory experiments. Boric acid is used in acid-base chemistry, buffer preparation, analytical procedures, qualitative inorganic analysis, and scientific investigations involving boron compounds. Its solubility in water increases with temperature, which is relevant to solution preparation and recrystallization studies. The Extra Pure designation identifies a commercial reagent grade, but suitability for a particular analytical method depends on the product’s actual specifications. This 500 g pack is convenient for laboratory inventory and controlled experimental use in schools, colleges, universities, and research centres. Appropriate protective equipment and chemical safety procedures should be followed during handling.

Is boric acid suitable for buffer preparation?

Boric acid can be used in selected borate buffer systems, particularly where the desired pH and experimental conditions are appropriate for borate equilibria. Buffer performance depends on the total borate concentration, pH, temperature, and solution composition. Use a validated preparation method and suitable reagents for analytical work.

How should Boric Acid Extra Pure be stored and handled?

Store boric acid in a tightly closed container in a dry, well-ventilated area, protected from contamination and moisture. Avoid generating dust and use suitable gloves, protective clothing, and eye protection. Boric acid may pose reproductive hazards, so consult the applicable Safety Data Sheet and follow institutional risk assessments and handling procedures.

Storage Conditions for Boric Acid Extra Pure

Store boric acid in its original, tightly closed, clearly labelled container in a cool, dry, well-ventilated location. Protect it from contamination, excessive moisture, and unnecessary exposure to heat. Keep it separated from incompatible materials, including strong bases where specified by the applicable Safety Data Sheet. Restrict access where required by the chemical risk assessment and applicable laboratory procedures.

Precautions for Handling Boric Acid Extra Pure

Review the applicable Safety Data Sheet before use and wear suitable chemical-resistant gloves, protective clothing, and safety goggles. Minimize dust generation and avoid inhalation or contact with the eyes and skin. Boric acid may damage fertility or the unborn child; apply the relevant reproductive-hazard controls and avoid exposure, particularly for pregnant personnel or those planning pregnancy. Use appropriate ventilation, clean spills according to approved procedures, and dispose of residues in accordance with institutional requirements and local regulations.
