Borax Granular – 500 gram Packs

Borax Granular is an inorganic sodium borate salt commonly identified as sodium tetraborate decahydrate, with the chemical formula Na₂B₄O₇·10H₂O. It is a white, crystalline granular solid that forms alkaline aqueous solutions and exhibits useful buffering and chemical reaction properties. Borax is widely used in educational and research laboratories for acid-base chemistry, buffer preparation, qualitative analysis, and investigations involving borate ions. It is also suitable for standardization of suitable acidic solutions and selected volumetric analysis procedures when the reagent grade and product specifications meet the method requirements. The granular form allows convenient handling and measurement during laboratory preparation. This 500 g pack is intended for laboratory stock and controlled experimental use in schools, colleges, universities, and research institutions. Appropriate personal protective equipment and safe chemical handling procedures should be followed during weighing, dissolution, and laboratory use.

Frequently Asked Questions About Borax Granular

What is Borax Granular used for in laboratories?

Borax Granular is used in acid-base experiments, borate buffer preparation, qualitative inorganic analysis, and selected volumetric procedures. Sodium tetraborate decahydrate can also be used to standardize suitable acidic solutions when its quality and handling meet the requirements of the analytical method.

What is the chemical formula of Borax Granular?

For borax decahydrate, the molecular formula is Na₂B₄O₇·10H₂O, representing sodium tetraborate with ten water molecules of crystallization. The formula mass is approximately 381.37 g/mol. Anhydrous sodium tetraborate has a different formula and molecular weight, so the hydrate form matters when calculating reagent quantities.

What is the CAS number and molecular weight of borax decahydrate?

The CAS Registry Number for sodium tetraborate decahydrate is 1303-96-4. Its molecular weight is approximately 381.37 g/mol. These values identify the decahydrate form and should not be confused with the corresponding values for anhydrous sodium tetraborate.

Can Borax Granular be used to prepare buffer solutions?

Yes. Borax can be used in preparing borate buffer systems for experiments requiring a suitable alkaline pH range. The final pH depends on concentration, temperature, and the composition of the buffer system. For analytical or research work, verify the buffer recipe and suitability against the requirements of the specific method.

How should Borax Granular be stored and handled safely?

Keep the material in a tightly closed, compatible container in a dry, well-ventilated location. Avoid generating or inhaling dust and prevent contact with eyes. Wear suitable gloves and safety goggles, wash hands after handling, and consult the applicable Safety Data Sheet for detailed precautions, exposure controls, and disposal requirements.

Storage Conditions for Borax Granular

Store Borax Granular in a tightly closed, clearly labelled, compatible container in a cool, dry, well-ventilated area. Protect it from contamination and unnecessary moisture exposure, and keep it separated from incompatible materials identified in the applicable Safety Data Sheet. Keep the container securely closed between uses to maintain material quality and prevent dust release during storage.

Precautions for Handling Borax Granular

Review the applicable Safety Data Sheet before use and wear suitable protective gloves, safety goggles, and laboratory clothing. Avoid generating dust and prevent inhalation or contact with the eyes. Use appropriate ventilation when weighing or transferring larger quantities, and clean spills using approved laboratory procedures that minimize dust dispersion. Do not ingest the reagent, and follow institutional requirements for waste disposal and chemical hygiene. Educational laboratory use should be supervised where required by the risk assessment.
