SECTION 10: STABILITY AND REACTIVITY
STABILITY:
This product is stable under normal conditions at ambient temperature.
INCOMPATIBILITY (MATERIAL TO AVOID):
Electrolyte: Contact with combustibles and organic materials may cause
fire and explosion. Also reacts violently with strong reducing agents,
metals, sulfur trioxide gas, strong oxidizers, and water. Contact with
metals may produce toxic sulfur dioxide fumes and may release
flammable hydrogen gas.
Lead compounds: Avoid contact with strong acids, bases, halides,
halogenates, potassium nitrate, permanganate, peroxides, nascent
hydrogen, and reducing agents.
Arsenic compounds: strong oxidizers; bromine azide. NOTE: hydrogen
gas can react with inorganic arsenic to form the highly toxic gas
-
arsine
HAZARDOUS DECOMPOSITION BY-
PRODUCTS:
Electrolyte: Sulfur trioxide, carbon monoxide, sulfuric acid mist, sulfur
dioxide, hydrogen sulfide.
Lead compounds: Temperatures above the melting point are likely to
produce toxic metal fume, vapor, or dust; contact with strong acid or
base or prescence of nascent hydrogen may generate highly toxic arsine
gas.
HAZARDOUS POLYMERIZATION:
Will not occur
CONDITIONS TO AVOID:
Prolonged overcharge at high current; sources of ignition.
