Acids are complex chemical compounds with a hydrogen atom at its core, moreover, a hydrogen atom can be easily replaced by a metal atom to obtain salts or other substances. This article will discuss one of the most toxic acids - sulfuric acid. By the way, earlier it was called "vitriol oil", which gave the name of its salts - vitriol.
The main characteristics of sulfuric acid.
Sulfuric acid is a viscous liquid that is colorless and odorless. The crystallization temperature is 10.4⁰C, and the boiling point is about 330⁰C. It is interesting that in nature it also occurs in a completely pure form.
In sulfuric acid chemically pure, the concentration of H₂SO₄ is about 96- 97%. As such, it usually goes on sale. It is easy to distinguish by weight due to its high density. 1 liter of such a substance weighs almost 2 kg.
Sulfuric acid has an amazing feature - it absorbs water, like a sponge, from the ambient air. This process takes place with the release of a huge amount of heat. This contributes to the carbonization of carbohydrate organics (for example, sugar, wood, etc.), which are subject to the influence of acid. It takes water molecules from carbohydrates, the remaining carbon is converted into coal. It can also be used to dry gases due to its active absorbent properties.
Due to the low fugacity of sulfuric acid, it is used to replace more volatile compounds in salts.
Reagent grade sulfuric acid with a density of 1.84 g / cm³ is widely used for the oxidation of various chemicals.
Sulfuric acid affects metals in completely different ways. Oxidation directly depends on its concentration. A weak solution can only oxidize with a hydrogen ion, as a result of which the acid can affect only those substances that are located in the line of activities before hydrogen. Among these metals is zinc. Lead is an exception, since the resulting compound PbSO₄ is a salt resistant to dissolution.
With concentrated sulfuric acid, the situation is different. The main conductor of the reaction is sulfur, which dissolves metals. They must be in a row not lower than silver, including itself. As a result of this combination, various chemicals are formed. It depends on the metal itself, temperature and concentration of H₂SO₄. For example, when oxidizing low-activity copper, we get sulfur dioxide - SO₂.
Sulfuric acid behaves differently with active chemicals. In the case of zinc, not only sulfur oxide can be released. With different metal activities, free sulfur and hydrogen sulfide also appear.
Sulfuric acid is used everywhere. Below we will consider the main directions.
Sulfuric acid reagent grade :
It belongs to precursors. In order to buy high-purity sulfuric acid, a special license is required. As a result, it is used quite little in everyday life. The most famous application for all motorists is the manufacture of a special solution that conducts current in batteries.
An interesting experience can be made for students with special equipment. Moistened granulated sugar is placed in a narrow tall glass and concentrated sulfuric acid is added. Then quickly and accurately the resulting mixture is stirred with a glass rod, which is then left in the glass. After a couple of minutes, the acid begins to react actively, taking water from the organic matter. Sugar is charred, blackening, slightly smoky and actively rises, giving off carbon dioxide and sulfurous gases.

However, Sulfuric acid is most widely used in various industries. It is not for nothing that it is called “bread”, and “blood”, and the “queen” of chemistry.
Metallurgy is simply unthinkable without sulfuric acid. With its help, uranium, iridium, zirconium and other rare metals are mined and processed.
The well-known mineral fertilizers, superphosphate and ammonium sulfate, are produced using sulfuric acid. They can be applied at any time of the year, so they are not washed out with precipitation. It is the manufacture of agricultural fertilizers that is the largest consumer of sulfuric acid. Such factories are often even united by one production complex.
Reagent grade sulfuric acid is used to release mineral salts and acids.
The production of paints, explosives, various chemical fibers is not complete without the use of this acid.
It is also widespread in the food industry as a well-known preservative E 513, improving the characteristics of flour and yeast dough.
Sulfuric acid is widely used in medicine. Its use varies considerably from compounds with other substances. It is both an antidote to poisoning with some heavy metals, and a remedy for the treatment of the skin (for example, scabies), and as an antispasmodic, and many other areas.
Rules of work with sulfuric acid.
It should be noted right away that sulfuric acid is very dangerous for humans. This acid is assigned the eighth hazard class. Causes severe burns on contact with skin, not to mention mucous membranes, or if swallowed. It should be remembered that, unlike thermal burns, it is not enough to simply rinse the affected area abundantly. At the beginning of the article, we already said that when interacting with water, a large release of heat occurs and a chemical reaction intensifies. Therefore, it is necessary to neutralize the affected area with a solution of soda (1 teaspoon per glass of water) or copious lather. After that, you should immediately seek medical help.
Harm to the human body can be caused not only by the acid solution, but also by its vapors. They can cause severe burns to the mucous membranes and pulmonary edema. The lethal dose if ingested is only 5 ml. How to protect yourself when working with high-density reagent grade sulfuric acid? To do this, the acid should be properly stored, used and disposed of.
If necessary, dilute - pour the acid into the water in a thin stream, and not vice versa, to avoid splashing and steam release.
One should carefully approach the choice of work clothes, constantly checking it for holes formed. It is strictly forbidden to pour sulfuric acid into the sewer - it can corrode downpipes, both iron and plastic. For disposal, it must be handed over to special services dealing with highly toxic waste.
The transportation and storage of sulfuric acid is no less important for compliance with safety measures than direct work with it. They use special containers made of metals that do not oxidize - these are titanium and steel. They are selected depending on the type and activity of sulfuric acid. During transportation, the thermal regime must be observed to prevent chemical reactions. You should also adhere to speed limits, avoid large crowds and label vehicles accordingly. Small volumes can be stored in glass containers with a plastic crate.
Where can you buy chemically pure sulfuric acid?
By purchasing sulfuric acid from trusted suppliers, you can avoid many risks associated with its transportation and proper storage. The company must have permits to trade in precursors , which includes acid. Sulfuric acid can be purchased in different concentrations, which allows it to be used for different needs. Manufacturers offer various volumes, convenient and safe delivery methods. Sulfuric acid reagent grade can be easily bought in almost any region of Ukraine. Experienced staff will even help you determine the volume and percentage you need, select the most convenient payment and transportation methods.
