Hi Ruel...
Sulfuric acid is a clear, colorless, oily, and odorless liquid. It is also
known as sulphine acid, battery acid, and hydrogen sulfate. More sulfuric
acid is produced in the United States than any other chemical. Its main
use is in phosphate fertilizer production. It is also used to manufacture
explosives, other acids, explosives, dyestuffs, parchment paper, glue,
wood preservatives, and lead-acid batteries in vehicles. It is used in the
purification of petroleum, the pickling of metal, electroplating baths,
nonferrous metallurgy, and production of rayon and film; and as a
laboratory reagent.
Sulfuric acid is very corrosive. It can be found in the air as small
droplets or it can be attached to other small particles in the air. When
concentrated sulfuric acid is mixed with water, the solution gets very
hot. Concentrated sulfuric acid can catch fire or explode when it comes
into contact with many chemicals, including acetone, alcohols, and metals.
When heated, it emits highly toxic fumes that include sulfur trioxide. It
is capable of igniting finely divided combustible materials. It is
incompatible or reactive with organic materials, chlorates, carbides,
fulminates, water, and powdered metals. It is soluble in water and ethyl
alcohol.
Sulfuric acid is very corrosive and irritating and can cause direct
effects on the skin, eyes, and respiratory and gastrointestinal tracts
when there is direct exposure to sufficient concentrations. It can cause
blindness if thrown on the eyes. Drinking concentrated sulfuric acid can
burn the mouth and throat, erode a hole in the stomach, and possibly cause
death. Breathing sulfuric acid mists can result in tooth erosion and
respiratory tract irritation. Breathing small droplets of sulfuric acid
that may be in polluted air may make it more difficult to breathe.
Breathing large amounts of sulfuric acid droplets will also decrease the
ability of the respiratory tract to remove other small particles in the
respiratory tract. Exposure through inhalation, ingestion, or contact with
the skin can cause pulmonary edema, bronchitis, emphysema, conjunctivitis,
stomatis, tracheobronchitis, and dermatitis
Sulfur Trioxide (SO3) also call sulfuric anhydride is listed by the EPA
and OSHA as a highly toxic substance. It can react in the atmosphere
with water to form sulfuric acid, which then reacts with ammonia or other
cations to form particles of ammonia sulfate or some other sulfate. These
small particles are responsible for urban particulate and visibility
problems. Reduction means the removal of oxygen or the addition of
hydrogen.
These chemicals are also produced in the burning of fossil fuels and
contribute to acid rain…Hope this helps….Mark
