An odorless yellow-green solid. Sinks in and mixes with water. A hydrate of
formula (H2SO4)2.3H2O is also known. (NOAA, 2003)

Section 2 – Hazards

Reactivity Alerts

  • Radioactive Material
Air & Water Reactions
Soluble in water.
Fire Hazard
No information available.
Health Hazard
Inhalation of dust may irritate nose and throat. Contact with eyes causes
irritation. (USCG, 1999)
Reactivity Profile
Inorganic oxidizing agents can react with reducing agents to generate heat and
products that may be gaseous (causing pressurization of closed containers).
The products may themselves be capable of further reactions (such as
combustion in the air). The chemical reduction of materials in this group can
be rapid or even explosive, but often requires initiation (heat, spark,
catalyst, addition of a solvent). Inorganic oxidizing agents can react
violently with active metals, cyanides, esters, and thiocyanates. Explosives
often consist of an inorganic oxidizing agent mixed in intimate contact with a
reducing agent. Gunpowder is such a mixture. Other examples are a mixture of
sugar (an organic compound) plus sodium chlorate and magnesium (an inorganic
reducing agent) plus barium peroxide. Compounds that inherently contain a
group that is a reducing agent and an oxidizing agent are classed in both
Group 44 (Inorganic Oxidizing Agents) and in Group 45 (Inorganic Reducing
Agents; for example, ammonium nitrate). The strongly oxidizing elements oxygen
and fluorine are classified here. Inorganic oxidizing agents that are also
acids (such as nitric and perchloric acids) are not included in this group.
They are in Group 2 (Acids, Inorganic Oxidizing). (REACTIVITY, 2003)
