Interested in where you can buy sulfuric acid, the first thing we recall about the properties of this dangerous substance for humans. Sulfuric acid is a variant of a strong dibasic acid, its formula is H ₂ SO ₄ . In Russia this mixture of sulfur trioxide with water is produced in accordance with GOST 667-73, 2184-77, 4240-77. The production of this heavy oily liquid, which does not possess either color or odor, suggests several of its varieties, which differ in their purity and concentration.

Sulfuric acid has the following important properties:

• The specific gravity is 1.85 g / cm ³ (for an ideal 100% sulfuric acid - 1.92 g / cm ³ , but this substance has a significant disadvantage - it freezes at -10 degrees Celsius).
• The boiling point is +296.5 ^° Celsius, the crystallization point is + 10.45 ° Celsius.
• At a concentration of up to 70%, only water vapor is released during the heating and boiling of this acid. With a larger H ₂ SO ₄ content, harmful acidic release also enters the air.
• Explosion and fire hazardous substance. When in contact with water, a violent reaction should be feared, as a result of which gases, vapors, and heat are released. Therefore, when working with sulfuric acid, you need to have special clothes, shoes, a set of individual chemical protection.

Deliver to the end user sulfuric acid both by road and rail. Special sulfuric acid packagings (for technical sulfuric acid) or acid-resistant tanks (for improved H ₂ SO ₄₎ are used for transportation _.

At storage it is necessary to remember that sulfuric acid is a toxic substance belonging to the second class of danger. The extremely safe concentration of H ₂ SO ₄ vapor is 1 mg / m ³ . Before deciding where to buy sulfuric acid (technical), you need to purchase a special container for its storage. In production facilities, it is additionally covered with acid-resistant brick.

Application of sulfuric acid

The main consumers of sulfuric acid are metallurgical enterprises, woodworking plants, chemical industry. It is used for:

• Purification of petroleum products from sulphurous inclusions;
• Decomposition of ore;
• Removal of scale before galvanizing wire, metal sheets;
• Nickel plating, chromium plating of metal surface;
• Production of medicinal products (concentrated solution in organic synthesis);
• Production of fertilizers (this industry consumes about half of all produced sulfuric acid in the country);
• Manufacture of artificial fiber;
• Production of ethyl alcohol;
• The production of aniline dye.

Private persons interested in where to buy sulfuric acid, mainly use it as an electrolyte for acid batteries.

So, it is important to keep in mind the following:

1. In rare cases, a private person will be sold a large amount of this substance - it should be purchased little by little, from different suppliers.
2. If it is not possible to purchase, you can try evaporating H ₂ SO ₄ from the electrolyte. The maximum density in this case will not be more than 1.4 g / cm ³ . Evaporation is carried out in a porcelain container on a sand or gypsum bath. In no event can this process be carried out indoors.
3. Remember that the sale of sulfuric acid is under control; This substance is used for the production of drugs, as well as improvised explosives. Even if you acquire it for innocent experiments or for refueling the auto accumulator in quite large quantities, this can cause unnecessary suspicion.
