Sodium Sulphide
Sodium Sulphide (Product Code: SCL-969/227) is a strongly alkaline sodium salt used as a ready source of sulphide ions for precipitating metal sulphides and preparing positive controls in qualitative analysis. Chemistry teachers and analysts use the 500 gm pack, which is analytical reagent grade and supplied with an MSDS, in schools, colleges and research labs. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory chemicals supplier in India for inorganic analysis work.

What Is Sodium Sulphide Used For?
A freshly made sulphide solution added drop-wise to different metal salt solutions produces a striking series of precipitates: black with lead and copper salts, white with zinc, yellow with cadmium and a pale pink with manganese. Teachers use this row of test tubes to explain why metal ions are separated into groups in qualitative analysis. The same solution provides a reliable positive control for the violet sodium nitroprusside test and for blackening lead acetate paper.
Sodium sulphide is corrosive to skin and eyes, and any contact with acid releases toxic hydrogen sulphide gas, so every step that acidifies a sulphide solution belongs inside a chemical fume cupboard. The solid readily absorbs moisture and slowly yellows in air, so reclose the container straight after weighing and store it well away from acids. Wear gloves and eye protection, and dispose of sulphide residues as the MSDS directs rather than pouring them into an acidic sink.
Supplier

Frequently Asked Questions
Who supplies Sodium Sulphide SCL-969/227?
Sodium Sulphide (SCL-969/227) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. The company sources this analytical reagent in 500 gm packs, each with an MSDS, for schools, colleges and research laboratories in India and international markets.
Why does Sodium Sulphide turn yellow after opening?
Sodium Sulphide turns yellow because exposure to air and moisture slowly forms polysulphides on the surface. Keep the lid tightly closed straight after weighing, and for careful quantitative work use material from a freshly opened pack.
How should a Sodium Sulphide test solution be prepared?
Dissolve a small quantity of Sodium Sulphide in distilled water shortly before the practical. Sulphide solutions deteriorate on standing, so make only what the session needs, label the bottle clearly and never acidify it outside a fume cupboard.
What are the main hazards of Sodium Sulphide?
Sodium Sulphide is corrosive to skin and eyes and releases toxic hydrogen sulphide gas when it contacts acids. The MSDS supplied with the pack sets out protective equipment, first aid and spill handling; store it well away from acids.
What is the shelf life of Sodium Sulphide?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Each Sodium Sulphide pack holds 500 gm, so keep opened stock tightly closed and dry between sessions.
Can Sodium Sulphide be shipped abroad?
Sodium Sulphide is regulated for transport, so export packing and carrier acceptance depend on the destination. Share your country and quantity through our contact page, and we will give a confirmed answer before quoting for international delivery.
Can I order Sodium Sulphide together with other salt analysis reagents?
Yes. Add Sodium Sulphide and the other reagents you need, such as sodium nitroprusside and lead acetate, to the enquiry cart, and we will quote them in a single response for delivery in India or international markets.
