General Description

An odorless yellow-green solid. Sinks in and mixes with water. A hydrate of formula (H2SO4)2.7H2O is also known.

Air & Water Reactions

Soluble in water.

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).

Health Hazard

Inhalation of dust may irritate nose and throat. Contact with eyes causes irritation.
