Aluminium Sulphide – 500 gram Packs

Aluminium Sulphide is an inorganic binary compound formed from aluminium and sulfur, with the formula Al₂S₃. It is chemically distinct from aluminium sulfate and aluminium sulfite. Aluminium Sulphide reacts with water and moisture, producing aluminium hydroxide species and hydrogen sulfide gas, which is highly toxic. This reactivity makes it relevant to controlled inorganic chemistry investigations involving metal sulfides, hydrolysis, and gas-forming reactions, but it requires specialized precautions and is not suitable for routine unsupervised school demonstrations. Its use should be limited to appropriately equipped laboratories with trained personnel and documented risk controls. The actual material’s purity, condition, and handling requirements should be checked before any experimental use.

Why Choose Lab Wale to Buy Aluminium Sulphide

Lab Wale provides a sourcing option for laboratory chemicals and scientific supplies for institutional and research use. Aluminium Sulphide requires particularly careful identity verification, moisture control, and safety planning before purchase. Laboratories should confirm the chemical form, grade, product specifications, and applicable safety documentation before selecting it. Its use should be restricted to facilities capable of managing its water reactivity and the risk of hydrogen sulfide release.

Frequently Asked Questions About Aluminium Sulphide

What is the chemical formula of Aluminium Sulphide?

Aluminium Sulphide has the formula Al₂S₃ and a formula mass of approximately 150.16 g/mol. It is a binary inorganic compound and must not be confused with aluminium sulfate, Al₂(SO₄)₃, or aluminium sulfite.

What is the CAS number of Aluminium Sulphide?

The CAS number for aluminium sulfide, Al₂S₃, is 1302-81-4. Confirm the product label and supporting technical information before use, especially where the material is being purchased for a specialized reaction or research procedure.

Why must Aluminium Sulphide be protected from moisture?

Aluminium Sulphide reacts with water and moisture and can release hydrogen sulfide gas. Hydrogen sulfide is highly toxic, so moisture exposure can create a serious inhalation hazard. Keep the compound dry and follow the current Safety Data Sheet and institutional risk controls.

Is Aluminium Sulphide suitable for routine school experiments?

It is generally unsuitable for routine, unsupervised school demonstrations because of its reactivity with water and the potential release of toxic gas. Any use should require a documented risk assessment, trained supervision, appropriate containment, and suitable gas-control measures.

How should Aluminium Sulphide be stored and handled?

Protect it from moisture and store it in a compatible, tightly sealed container under the conditions specified in its Safety Data Sheet. Avoid contact with water, acids, and incompatible materials. Use suitable engineering controls and trained personnel, with emergency procedures in place for accidental exposure or gas release.

Storage Conditions for Aluminium Sulphide

Store Aluminium Sulphide in a dry, tightly sealed, compatible container under the conditions specified by the supplier. Prevent contact with water, moisture, acids, and incompatible chemicals. Use a designated storage arrangement based on the current Safety Data Sheet and institutional risk assessment, with controls to prevent accidental water ingress.

Precautions for Handling Aluminium Sulphide

Only trained personnel in suitably equipped laboratories should handle Aluminium Sulphide. Review the current Safety Data Sheet and risk assessment, prevent moisture contact, and use appropriate containment and protective equipment. Avoid dust exposure and any operation that could release hydrogen sulfide. Do not handle it in an ordinary teaching laboratory without appropriate controls, gas monitoring where required, and an approved emergency plan.
