What is Sulfuric Acid?
The sulfic acid is a colorless, odorless, and very corrosive liquid, made up of hydrogen, sulfur, and oxygen. The molecular formula of the sulfuric acid is H₂SO₄, made up of two hydrogen (H) molecules, one sulfur (S), and four oxygen (O) molecules. Because of its acidic nature and high reactivity with chemicals, sulfuric acid is widely utilized in many industries and chemical laboratories.
Important Properties of Sulfuric Acid
Before discussing the wide variety of applications of sulfuric acid, it is crucial to highlight some of its main physical and chemical properties. The chemical composition of sulfuric acid is represented by the following chemical formula – H₂SO₄, while the molecular weight of the compound equals 98.079 g/mol. Sulfuric acid appears as a clear and odorless liquid with such density equal to 1.84 g/cm³, with the boiling point of 337°C and melting point of 10°C. The compound is highly soluble in water; however, it reacts extremely violently in water mixture, producing a lot of heat. From the point of view of chemical properties, it is necessary to say that sulfuric acid belongs to strong mineral acids characterized by high corrosivity, dehydrating properties and oxidizing abilities; besides, it reacts with different metals to form hydrogen gas.
Sulfuric Acid Density
Sulfuric acid solution density is around 1.84 grams per cubic centimeter at 25°C, which makes it one of the most dense industrial acids in common use. Keeping the right density is necessary as it directly influences the concentration and performance of the acid. It plays an important role in industry as it allows to dose chemicals correctly, ensure efficient process control, get consistent product quality, conduct reliable laboratory analyses, and safely store and handle the substance.
Concentrated Sulfuric Acid
Commercial sulfuric acid usually has between 95% to 98% H2SO4. This is one of the most popular industrial chemicals. Sulfuric acid has very good dehydration, chemical stability, moisture absorption ability, and strong acidic properties. Also, this acid can be used as a catalyst in various chemical reactions. The above properties of sulfuric acid make it extremely useful in a variety of industries such as chemical production, petroleum refining, manufacture of medicines, manufacture of fertilizers, metal industry, and water treatment facilities.

This is extensively used in pH control, alkalinity control, pre-treatment for RO water purification, ETPs, and STPs. Another important use of sulfuric acid is in the treatment of cooling tower water, boiler feed water, and neutralizing wastewater in the industries. When used in appropriate doses, it increases the efficiency of the water treatment process, prevents scaling of water treatment equipment, and fulfills the requirements of the environmental regulations.
10 Uses of Sulphuric Acid
Sulfuric acid is amongst the most extensively utilized chemicals in industries, being used in various industries for different purposes. The ten main uses of sulfuric acid include the production of phosphate fertilizers, preparation of lead-acid batteries, petrochemical refining, water purification, detergent production, dye production, manufacture of medicines, steel pickling, mineral processing in the mining industry, and chemical synthesis. Due to its high acidic nature and reactivity along with affordability, sulfuric acid becomes very important in increasing the efficiency of the industries and large-scale manufacturing process.
Sulfuric Acid Uses in Everyday Life
Although the use of pure sulfuric acid is very uncommon in households due to its highly corrosive nature, the acid is very significant in the manufacturing of various materials which are used on a daily basis. The acid is required in the production of batteries, water purifiers, fertilizers, cleaning substances, papers, and medicines. Although people do not use pure sulfuric acid in their households, it is of high significance in the production of various materials which make it significant in their daily lives.
Sulfuric Acid Uses in Medicine
Sulfuric acid does not have any direct applications in medicine, but it has immense importance in the manufacturing process of medicines and the chemical industry. Sulfuric acid is mainly used in the synthesis of pharmaceutical compounds, in pharmaceutical intermediate manufacture, in laboratories for experiments, and in the manufacture of APIs. Because of its strong acidic nature and acting as a catalyst, sulfuric acid assists in different chemical reactions for the creation of good medicines.
Is Sulfuric Acid Used in the Human Body?
A lot of individuals have searched for Uses of Sulphuric acid in human body.
The response is No. Sulfuric acid is not produced nor used by the human body. The acid formed in the stomach is HCL or hydrochloric acid.
Sulfuric Acid Uses for Skin
Any application of sulfuric acid on the skin should never be done under any circumstances because it is a hazardous material that could result in grave injuries when applied. There is a likelihood of suffering from serious chemical burns, skin irritation, tissue damage, and permanent injuries when exposed to sulfuric acid. Proper PPE should be worn by any personnel working with sulfuric acid.
Sulfuric Acid Price
There are several parameters that affect the cost of sulfuric acid, which include its purity level (e.g., 98% sulfuric acid), the type of product (industrial or laboratory sulfuric acid), order volume, packing, logistics expenses, and location of the vendor. Generally, the price per unit for bulk orders is cheaper than the price per unit for laboratory volumes.
Case Study: Making Water Treatment Process More Efficient
There exists a small to medium-sized factory that was experiencing the problem of scaling and pH fluctuations at their water treatment facility. To solve these problems, they applied an automated sulfuric acid dosing system. This helped them stabilize the pH value, reduce wastage of chemicals, prolong the life of RO membranes, cut down on maintenance costs, and maintain the quality of water continuously. From the case study above, it can be concluded that proper use of sulfuric acid during the process of water treatment makes it more efficient.
Manufacturing Process of Sulfuric Acid
The production of sulfuric acid mainly occurs through the Contact Process, which is the most efficient method that has been embraced globally to manufacture pure sulfuric acid. Through this process, the sulfur undergoes combustion to yield sulfur dioxide (SO₂). It is then converted to sulfur trioxide (SO₃) using a catalyst. Sulfur trioxide is absorbed in concentrated sulfuric acid to yield oleum, which is diluted with water under strict control to give rise to sulfuric acid.
Storage and Safety Guidelines
Sulfuric acid is a very corrosive chemical substance, which needs to be handled with maximum caution in order to keep the surroundings safe. The sulfuric acid should always be stored in containers that are resistant to chemicals and should always be kept away from other chemicals, which react with them. Every person handling sulfuric acid should always use personal protective equipment such as chemical-resistant gloves, safety goggles, eye shield, and protective clothing. Proper ventilation is always required in the place where the work is done. All industrial safety measures for chemicals should always be followed strictly.
