REACTIVITY DATA
Stability: Stable
Condition to Avoid: Prolonged overcharging, sources of ignition
Incompatibility (Materials to Avoid): Sulfuric Acid: Contact with combustibles and organic materials may cause fire and explosion.
Also reacts violently with strong reducing agents, metals, strong oxidizers and water.
Contact with metals may produce toxic sulfur dioxide fumes and may release flammable
hydrogen gas.
Hazardous Decomposition of By-Products:
Sulfuric Acid: Excessive overcharging or fire may create sulfur trioxide, carbon
monoxide, sulfuric acid mist, sulfur dioxide, and hydrogen.
Lead Compounds: Contact with strong acid or base presence of nascent hydrogen
may generate highly toxic arsenic gas.
