Sodium Hydrogen Phosphate- 1 Kg Packs

Sodium Hydrogen Phosphate is a laboratory catalog product associated with phosphate buffer salt and scientific work involving conjugate acid–base phosphate equilibria. Its common dibasic identity supplies hydrogen phosphate ions, but the catalog name does not establish hydration. The exact chemical identification is important for interpreting stoichiometry, test outcomes, solubility and reagent compatibility. Teaching laboratories and analytical research groups may use appropriately selected materials for established investigations, but the actual experimental purpose must match the supplied composition and grade. In particular, controlled work with this product can illustrate characteristic inorganic or solution chemistry while strengthening an understanding of reaction mechanisms and analytical observations. It should not be treated as universally suitable for classroom or quantitative procedures. Personnel must consider the substance-specific hazards, proper protective equipment, incompatible reagents and regulated disposal before using this material. Where the product name does not establish hydration, composition or a unique identity, confirm these details from its original supplier documentation before use.

Frequently Asked Questions About Sodium Hydrogen Phosphate

What are the main laboratory uses of Sodium Hydrogen Phosphate?

This material is associated with conjugate acid–base phosphate equilibria. Typical contexts include buffer capacity experiments with verified formulation and phosphate system titrations. Each use requires an appropriate method, confirmed identity and suitable handling controls; restricted or highly reactive substances should not be used in unsupervised student exercises.

What formula and molecular weight apply to Sodium Hydrogen Phosphate?

The applicable formula entry is Na2HPO4 (anhydrous basis), with a formula-mass entry of 141.96 (anhydrous). Some product names cover hydrated, commercial or mixed forms, so a theoretical formula does not necessarily describe the supplied material. Check the container label and relevant supplier documents before using these figures in calculations.

What CAS number identifies Sodium Hydrogen Phosphate?

The identifier information for this listing is 7558-79-4 (anhydrous); hydrate varies. This refers to the stated chemical basis where indicated; the actual product may require a different hydrate or composition identifier. Never substitute the CAS of a related compound solely because its trade name appears similar.

Is Sodium Hydrogen Phosphate suitable for college and research laboratories?

This reagent may support selected supervised analytical or research procedures where its form, grade and risks have been evaluated. It is not automatically appropriate for every method or for ordinary school practicals. The institution should establish controls based on the current safety data and procedure.

How should Sodium Hydrogen Phosphate be stored and handled?

Use a clearly labelled compatible container and follow the supplied Safety Data Sheet for exposure controls, incompatibilities, ventilation and spill response. Some salts are oxidizers, corrosive or moisture sensitive, and sodium metal requires specialist water-reactive handling. Collect residues through the institutional hazardous-waste procedure.

Storage Conditions for Sodium Hydrogen Phosphate

Store Sodium Hydrogen Phosphate in its appropriate tightly closed, clearly labelled and compatible container, protected from moisture, excess heat and accidental contamination. Separate from incompatible substances identified in the applicable Safety Data Sheet and maintain suitable access controls. Confirm any additional moisture, light and chemical segregation requirements from the product-specific documentation before storing a new lot.

Precautions for Handling Sodium Hydrogen Phosphate

Review the current Safety Data Sheet for Sodium Hydrogen Phosphate before handling. Wear suitable chemical-resistant gloves, eye protection and laboratory clothing, and use adequate ventilation or local containment as required. Avoid inhaling dust, contacting eyes or skin, and mixing with incompatible chemicals. Collect spills and wastes according to the approved institutional procedure; ensure appropriate supervision for hazardous experiments.
