The original sulphuric acid industry was largely based on recipes developed by craftsmen themselves, but by the end of the 19th century chemical research played an important role. By then, the once dominant lead-chamber process was competing against a new method known as the contact process. By the end of the First World War, the contact process had taken over world markets and most sulphuric acid today is produced in this way. The new method produced a purer form of sulphuric acid--up to 98 per cent--which was required by new markets for alizarin, indigo, and other synthetic pigments used by the textile industry.

The problem was solved by a comprehensive research program implemented by the large German industry group BASF Badische Anilin und Soda Fabrikation and led by the industrial chemist Rudolf Knietsch to in the s. Under normal circumstances, the combustion products of sulphuric acid, sulphur dioxide SO 2 , does not bind with oxygen in the air.
But the German chemist showed that it can be achieved by contact with a suitable catalyst, such as platinum or vanadium oxide V 2 O 5. BASF and another German manufacturer, Hoechst, established the first industrial plant based using the contact process in the mid s. Sulphuric acid is probably not a common household product. It is probably best known as battery acid, which together with distilled water is used in car batteries. But this does not change the fact that our society depends on it.
Sulphuric acid is an immeasurably important chemical, but it is not a good idea to come too close. We can be glad that we do not live on Venus, where not only is the surface temperature a searing degrees centigrade, but the atmosphere is formed of carbon dioxide and sulphuric acid.

Type a word, a phrase, or ask a question. Class E. Main Routes of Exposure: Inhalation. Skin contact. Eye contact. Inhalation: Not expected to be an inhalation hazard unless heated or misted. Can cause severe irritation of the nose and throat. Can cause life-threatening accumulation of fluid in the lungs pulmonary edema.
Symptoms may include coughing, shortness of breath, difficult breathing and tightness in the chest. Long-term damage may result from a severe short-term exposure. Contact can cause pain, redness, burns, and blistering. Permanent scarring can result. A severe exposure can cause death. Contact causes severe burns with redness, swelling, pain and blurred vision. Permanent damage including blindness can result. Ingestion: Can burn the lips, tongue, throat and stomach.
Symptoms may include nausea, vomiting, stomach cramps and diarrhea. Permanent damage can result. Can cause death. Effects of Long-Term Chronic Exposure: At low concentrations: Can cause dry, red, cracked skin dermatitis following skin contact.
At high concentrations: May wear away tooth enamel when breathed in. May harm the respiratory system. Can irritate and inflame the airways. Carcinogenicity: Not known to cause cancer.

Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms. This can include rain, snow, fog, hail or even dust that is acidic. Acid rain results when sulfur dioxide SO 2 and nitrogen oxides NO X are emitted into the atmosphere and transported by wind and air currents. These then mix with water and other materials before falling to the ground.
While a small portion of the SO 2 and NO X that cause acid rain is from natural sources such as volcanoes, most of it comes from the burning of fossil fuels.
Although sulfuric acid is not found in motor vehicle exhaust, it may be produced by the reaction of sulfur dioxide in the exhaust with other chemicals. Hard surface cleaners, metal cleaners, pool chemicals, car, motorcycle, truck and boat batteries.
Skip to main content. Sulfuric acid Overview Health effects Environmental effects Sources of emissions References Description Sulfuric acid is the world's largest volume industrial chemical. Melting Point: Australia's Sulfuric acid emission report.
Description Sulfuric acid is a corrosive chemical and can severely burn the skin and eyes. Entering the body Sulfuric acid will enter the body if we breathe in contaminated air.
Exposure Consumers are most likely to be exposed to sulfuric acid when using products containing the substance e. Drinking water guidelines There is no guideline for sulfuric acid in the Australian Drinking Water Guidelines. Description Sulfuric acid will exist as particles or droplets in the air if released to the atmosphere. Entering the environment Industrial emissions of sulfuric acid can produce elevated concentrations in the atmosphere.
Where it ends up Sulfuric acid enters the air during production, use and transporting it. Industry sources The primary sources of sulfuric acid emissions are the industries that manufacture it or use it in production. Diffuse sources, and industry sources included in diffuse emissions data Other possible emitters of sulfuric acid are home and larger pool treatment, the disposal of automobile batteries, electroplating facilities, electronics, semiconductor and circuit board production, potato growers, and water and waste water treatment.
