The production of this heavy oily liquid, which has neither color nor smell, suggests several varieties of it, 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 it is 1.92 g / cm ³ ; but such a substance has a significant minus - 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 heating and boiling of this acid. With a higher content of H ₂ SO ₄ , harmful acid emissions also enter the air.
• Explosive and fire hazardous substance. In contact with water, one should be wary of a violent reaction, 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.

Sulfuric acid is delivered to the end user both by road and by rail. For transportation, special sulfuric acid containers (for technical sulfuric acid) or acid-resistant tanks (for improved H ₂ SO _{4) are used.}

During storage, it is worth remembering that sulfuric acid is a toxic substance belonging to the second hazard class. Extremely safe vapor concentration of H ₂ SO ₄ is 1 mg / m ³ . Before deciding where to buy sulfuric acid (technical), you need to purchase a special container for its storage. In industrial premises, it is additionally lined with acid-resistant brick.

The use of sulfuric acid

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

• purification of petroleum products from sulfur inclusions;
• ore decomposition;
• descaling before galvanizing wire, metal sheets;
• nickel plating, chromium plating of the metal surface;
• production of medicines (concentrated solution in organic synthesis);
• fertilizer production (this industry consumes about half of all sulfuric acid produced in the country);
• manufacturing artificial fiber;
• ethanol production;
• making aniline dye.

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

Before you find out where to buy sulfuric acid, here are the tips of the people who made such an acquisition.

Buying Tips

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

1. In rare cases, a large volume of this substance will be sold to an individual - it should be purchased little by little, from different suppliers.
2. If purchase is not possible, you can try to evaporate H ₂ SO ₄ from the electrolyte. The maximum density will be no more than 1.4 g / cm ³ . Evaporation is carried out in a porcelain container in a sand or gypsum bath. In no case should this process be carried out indoors.
3. Remember that the sale of sulfuric acid is under control, as This substance is used to produce drugs as well as improvised explosives. Even if you purchase it for innocent experiments or for refueling the car battery in considerable quantities, this can cause unnecessary suspicions.
