Hazard Information

Chemical Properties

Mercuric sulfate is a white, odorless, crystalline solid

Chemical Properties

White crystals or powder. Mercuric sulphate decomposes on contact with water into yellow insoluble basic sulphate and sulphuric acid. The products of decomposition of mercuric sulphate include oxides of sulphur and oxides of mercury. Mercuric sulphate is incompatible with acetylene, ammonia, and strong acids and corrosive to iron, magnesium, aluminium, zinc, lead, and copper.

General Description

Odorless white granules or crystalline powder. Denser than water. MERCURIC SULFATE(7783-35-9) is toxic by inhalation and by ingestion. MERCURIC SULFATE(7783-35-9) is used in medicine, for gold and silver extraction, and to make other mercury compounds.

Reactivity Profile

The absorption of gaseous hydrogen chloride on MERCURIC SULFATE becomes violent at 125° C [Mellor 2, Supp. 1:462. 1956].

Air & Water Reactions

Decomposed by water to yellow mercuric subsulfate and sulfuric acid, which is corrosive.

Hazard

Highly toxic by ingestion, inhalation, and skin absorption.

Health Hazard

INHALATION: Acute poisoning: Tightness in chest, breathing difficulty, coughing, and pain. EYES: Ulceration of conjunctiva and cornea. SKIN: Irritation; may cause sensitization dermatitis. INGESTION: Necrosis, pain, vomiting, severe purging. Patient may die within a few hours from peripheral vascular collapse.

Potential Exposure

Mercuric sulfate is used in making other chemicals; as a battery electrolyte and in extracting gold and silver from rock

Fire Hazard

Special Hazards of Combustion Products: None

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, ge medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy
Antidotes and Special Procedures for medical personnel: The drug NAP has been used to treat mercury poisoning with limited success

Shipping

UN1645 Mercury sulfates, Hazard Class: 6.1; Labels: 6.1-Poisonous materials

Incompatibilities

Contact with water produces sulfuric acide and insoluble basic mercuric subsulfate. Reacts with acids producing mercury vapors. Violent reaction with gaseous hydrogen chloride above 121C. Decomposes in heat or on exposure to light, producing toxic fumes of mercury and sulfur oxides. Attacks magnesium, aluminum, zinc, iron, lead, copper.

Description

Mercuric sulfate is a white, odorless, crystalline solid. Molecular weight= 296.65; Freezing/Melting point=(decomposes). Hazard Identification (based on NFPA-704 M Rating System): Health 3, Flammability 0, Reactivity 0. Decomposes in water.

storage

Color Code—Blue: Health Hazard/Poison: Store in a secure poison location. Prior to working with this chemical you should be trained on its proper handling and storage. Store in tightly closed containers in a cool, wellventilated area away from light, water, and gaseous hydrogen chloride.
