Chlorine is not flammable but may react explosively or form explosive compounds with many common substances (including acetylene, ammonia, natural gas, and hydrogen)
Chlorine is slightly water soluble and reacts with moisture to form hydrochloric acid (HCl).
Chlorine is commonly pressurized and cooledfor storage and shipment.
It is produced commercially by electrolysis of sodium chloride brine.
