Sulfuric Acid

In this article, we will learn about the sulfuric acid, physical properties, chemical properties, occurrence, manufacture and uses.

Sulfuric acid is a viscous, oily liquid that is colourless to dark brown in colour and mixes completely with water. Its colour is determined by its purity, with sulphur components giving the colourless pure product a deeper hue. Sulfuric acid can also be found as fuming sulfuric acid, which is a sulphur trioxide solution in sulfuric acid with the chemical formula xH2SO4ySO3. Sulfuric acid is the most widely produced chemical on the planet. In 2004, the chemical sector produced 37,515,000 metric tonnes (41,266,000 short tonnes), with fertilisers accounting for more than half of the total. 

Physical properties of sulfuric acid:

  1. Sulfuric acid is a viscous, colourless, oily liquid.

  2. At 298 K, it has a specific gravity of 1.84.

  3. The acid’s boiling point is 611 K. Because of hydrogen bonding, this molecule has a greater boiling point and thickness.

  4. This powerful chemical reacts violently with water, releasing a large amount of. As a result, you should never mix H2SO4 with water. Instead, slowly add the acid to the water while stirring constantly. 

Chemical properties of sulfuric acid:

  1. Sulfuric acid is a dibasic acid with a high molecular weight. It’s also diprotic, ionising in two steps in aqueous solution.

  2. This substance is very corrosive, reactive, and water soluble. It has a high oxidising power, making it a powerful oxidising agent.

  3. It has a low level of volatility. As a result, it aids in the synthesis of more volatile acids from their contrasting salts.

  4. Sulfuric acid in concentrated form is a powerful dehydrator. As a result, this chemical is utilised to dry a variety of wet gases that do not react with acid.

  5. It also removes water from natural mixtures such as starches.

  6. It can oxidise both nonmetals and metals because it is a good oxidising agent. Furthermore, it decomposes into sulphur dioxide. 

Occurrence:

Due to its high affinity for water, pure sulfuric acid does not occur naturally on Earth in anhydrous form. Acid rain contains dilute sulfuric acid, which is created when sulphur dioxide is oxidised in the presence of water in the atmosphere, resulting in sulphurous acid oxidation. Sulphur dioxide is the major byproduct of burning sulphur-containing fuels like coal or oil (besides the chief products carbon oxides and water). 

Sulfuric acid is produced naturally when sulphide minerals, such as iron sulphide, are oxidised. Acid mine drainage (AMD) or acid rock drainage refers to the highly acidic water that results (ARD). This acidic water has the ability to dissolve metals in sulphide ores, resulting in brilliantly coloured, poisonous solutions. 

Sulfuric acid zinc oxide word equation:

Sulphuric acid reacts with zinc oxide to produce salt and water. Because of the basic nature of zinc oxide, this occurs (metallic oxides are basic in nature). When acids and bases react, the result is salt and water. 

ZnO + H2SO4 →ZnSO4 + H2O 

Uses of sulfuric acid:

The creation of phosphoric acid (H3PO4), which is then used to make fertilisers, is the most important single use of sulfuric acid. This use uses over 70% of all sulfuric acid used in the United States. Other applications for sulfuric acid include: 

  1. For the purification of gasoline and other petrochemicals, as a means of eliminating impurities; 

  2. For storage batteries (the liquid through which charged particles flow); 

  3. For the purification of gasoline and other petrochemicals, as a means of removing impurities present in the goods;

  4. As a cleaning agent for metal surfaces, particularly prior to plating with a second metal; 

  5. In the production of explosives, dyes, glues, pigments, rayon, and films; 

  6. As a catalyst in a range of industrial and research chemical reactions; 

  7. In the preparation of ores for metal extraction. 

Conclusion:

Mattling acid and Oil of Vitriol are two names for sulfuric acid. It’s caustic and has a strong acidic tendency. It has oxidising and dehydrating properties at greater doses. It’s a colourless, syrupy liquid with no odour. When dissolved in water, it is water soluble and produces heat. It’s a common ingredient in fertiliser manufacture. Chemical synthesis and wastewater treatment are two further applications. The dielectric constant of anhydrous sulfuric acid is roughly 100, making it a polar liquid. It’s the most important heavy industrial chemical, with large-scale applications in a variety of industries.
