Mercuric Chloride
Mercuric Chloride (Product Code: SCL-890/188) is mercury(II) chloride, a highly toxic inorganic salt used for the tin(II) confirmatory test and for preparing Nessler's reagent in college and university chemistry labs. The small 100 gm analytical reagent pack, sent with an MSDS, suits a chemical that is used a few drops at a time and kept under strict control. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to institutions with trained laboratory staff.

What Is Mercuric Chloride Used For?
In the analysis of Group II cations, a few drops of mercuric chloride solution added to a tin(II) solution give a silky white precipitate of mercurous chloride, which turns grey or black as more tin(II) reduces it to mercury – a clear confirmatory test for stannous ions. Laboratories that make their own Nessler's reagent start from mercuric chloride and potassium iodide in alkaline solution; the finished reagent reveals ammonia and ammonium ions in water analysis as a yellow to brown colour. Adding potassium iodide solution drop by drop to mercuric chloride also demonstrates a scarlet precipitate of mercury(II) iodide that dissolves again in excess iodide.
Mercuric chloride is highly toxic if swallowed, if its dust is inhaled or if it is absorbed through the skin, and it damages the kidneys and the environment. For that reason many schools buy ready-made Nessler's reagent rather than keeping the solid. Where it is held, keep it in a locked chemistry reagent cabinet with a usage log, weigh it only inside a fume cupboard wearing nitrile gloves and eye protection, and collect every residue as mercury waste for a licensed disposal service.
Supplier

Reagents used with mercuric chloride, a lower-handling alternative, and the storage and protection it demands:
- Nesslers Reagent — ready-made ammonia test reagent that avoids weighing the solid salt
- Potassium Iodide — reacts with mercuric chloride and is needed to prepare Nessler's reagent
- Tin Chloride (II) — the stannous salt used to practise the confirmatory test
- Hazardous Storage Cabinet Horizontal — dedicated storage that keeps toxic chemicals apart
- Gloves W/o Powder Nitrile Disposable — hand protection while weighing and dissolving the salt

Frequently Asked Questions
Who supplies Mercuric Chloride SCL-890/188?
Mercuric Chloride (SCL-890/188) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. The company sources this analytical reagent and dispatches each 100 gm pack with its MSDS to institutional laboratories in India and international markets, subject to toxic-chemical rules.
Who should handle mercuric chloride?
Only trained teachers and laboratory technicians should handle Mercuric Chloride. Students should receive, at most, small volumes of dilute test solution prepared by staff, and every use of the solid should be recorded in the hazardous-substance log.
Is there a safer option than mercuric chloride for the ammonia test?
Yes. Ready-made Nessler's reagent removes the need to store and weigh solid Mercuric Chloride, although it also contains mercury and must be handled with care. It is linked under the related products on this page.
What is the shelf life of Mercuric Chloride?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Mercuric Chloride is used only a few drops at a time, so one 100 gm pack lasts a long time when kept closed and locked.
How should mercuric chloride spills and waste be handled?
Follow the MSDS supplied with Mercuric Chloride: avoid raising dust, collect spilled material with a damp absorbent, and label it and all residues as mercury waste for a licensed disposal service. Nothing containing mercury should go down the drain.
Can Mercuric Chloride be exported?
Trade in mercury compounds is restricted in many countries, and Mercuric Chloride is also a toxic substance for transport. Tell us the destination through our contact page before ordering, and we will confirm whether it can be supplied there.
Request a Quote
Institutions needing Mercuric Chloride (SCL-890/188) can request a quotation through our contact page or add it to the enquiry cart, stating the intended use and the responsible staff member. Supply in India and international markets follows the rules that apply to toxic chemicals.
