Borax Extra Pure, also known as sodium tetraborate decahydrate, is a high-purity crystalline compound widely used in laboratory applications involving buffer preparation, flame tests, and qualitative inorganic analysis. It serves as a valuable reagent in analytical chemistry for detecting metal ions, especially in borax bead tests, and is commonly used to prepare borate buffers for biochemical experiments due to its stable pH-regulating properties. Its ability to act as a mild alkali and complexing agent makes it suitable for various titration and solubility studies. The extra pure grade guarantees minimal contamination, ensuring accurate and consistent results in sensitive laboratory work. It should be stored in a tightly sealed container in a cool, dry environment, away from acids and moisture.

Borax Extra Pure

Primary Uses

Buffering Agent
- Commonly used in preparing buffer solutions, especially in biochemical and enzymatic experiments due to its ability to maintain stable pH in alkaline ranges (pH ~9.2 when mixed with boric acid).
Complexometric Titration Support
- Acts as a masking or stabilizing agent in EDTA titrations, helping to maintain proper metal ion balance.
Reagent in Qualitative Inorganic Analysis
- Used in borax bead tests to identify transition metal ions based on the color of the molten bead formed upon heating with metal salts.
Glass and Enamel Flux Studies
- Serves in research on glass formation and enamel behavior, where borax acts as a fluxing agent that lowers melting points and enhances flow properties.

Secondary Uses

Microbiology & Molecular Biology Support
- Occasionally used in storage solutions for biological samples or as a component of certain staining buffers (e.g., in RNA gels).
Demonstration of Hydration and Crystal Structures
- In educational labs, borax crystals are used to teach crystallization, water of hydration, and thermochemical changes.
Polymer Slime Demonstrations
- Reacts with polyvinyl alcohol (PVA) in polymer cross-linking experiments, popular in educational chemistry demonstrations.
Water Softening & Ion Exchange Experiments
- Used in teaching water hardness reduction, due to its mild alkalinity and ion-complexing ability.
