Reactions of Sulfuric Acid
- Dissociation- When pure water-free sulphuric acid is cooked, sulfur trioxide and water are formed.
H2SO4 → SO3 + H2O
- Acidic Character of Sulphuric Acid- It’s a common dibasic acid that turns blue litmus crimson when exposed to it. It divides into two groups of salts.
NaOH + H2SO4 → NaHSO4 + H2O
2NaOH + H2SO4 → Na2SO4 + 2H2O
- Sulphonating Action of Sulphuric Acid- Concentrated sulphuric acid combines with a variety of organic molecules, such as benzene, toluene, and others, to form sulphonic acids, as an example.
C6H6 + H2SO4 → C6H5SO3H + H2O
- Precipitation Reactions with Sulphuric Acid- It creates insoluble sulfates that precipitate when handled with aqueous solutions of barium, lead, and other salts, for example.
H2SO4 + BaCl2 → BaSO4↓ + 2HCl
- Reaction with Sulphur Trioxide- Oleum, commonly known as fuming sulphuric acid, is formed when it dissolves sulfur trioxide.
H2SO4 + SO3 → H2S2O7
Sulfuric Acid – H2SO4
Sulfuric Acid or Sulphuric Acid is a mineral acid consisting of one Sulfur, four Oxygen, and two Hydrogen atoms. The chemical or molecular formula of Sulfuric Acid is H2SO4. Sulfuric Acid is one most important commercially used chemicals. It is also known as Mattling acid or Hydrogen Sulfate or Vitriol. Sulphuric acid is a very strong acid and viscous liquid. It is a colorless, odorless, oily liquid, and corrosive in nature. Sulfuric acid is a component of acid rain as it is soluble in water.
Sulfuric acid is a highly acidic liquid. As a result, it is used for the cleaning of metals, the extraction of impurities from oil, the production of chemicals such as nitric acid and hydrochloric acid, and the manufacture of dye, medicines, detergents, and explosives, among other processes. The molar mass of Sulfuric Acid is 98.079 g/mol. The density of Sulfuric acid is 1.83 g/cm3. The H2SO4 molecule is covalent and has a tetrahedral structure and monoclinic crystal structure.
