Sodium Dichromate Extra Pure – 500 gram Packs

Sodium Dichromate Extra Pure is a laboratory catalog product associated with chromium(VI) oxidizing salt and scientific work involving redox chemistry and chromium(VI) equilibria. The dichromate ion is an oxidizing agent and changes equilibrium with chromate according to acidity. 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 Dichromate Extra Pure

What are the main laboratory uses of Sodium Dichromate Extra Pure?

This material is associated with redox chemistry and chromium(VI) equilibria. Typical contexts include redox stoichiometry investigations and chromate–dichromate equilibrium studies. 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 Dichromate Extra Pure?

The applicable formula entry is Na2Cr2O7 (anhydrous basis), with a formula-mass entry of 261.97 (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 Dichromate Extra Pure?

The identifier information for this listing is 10588-01-9 (anhydrous); 7789-12-0 (dihydrate). 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 Dichromate Extra Pure 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 Dichromate Extra Pure 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 Dichromate Extra Pure

Store closed and secured in a dry oxidizer-compatible area, apart from combustible and reducing materials and with controls appropriate to toxic chromium(VI) compounds. Confirm any additional moisture, light and chemical segregation requirements from the product-specific documentation before storing a new lot.

Precautions for Handling Sodium Dichromate Extra Pure

Sodium dichromate is an oxidizing, toxic chromium(VI) material with serious chronic health hazards. Work only under approved institutional procedures with containment and protective equipment. Segregate all chromium-contaminated waste. Review the current Safety Data Sheet, use suitable protective gloves and eye protection, and apply approved spill response and waste segregation procedures. Restrict handling to trained laboratory personnel and avoid environmental release.
