Introduction: What is Sulphuric Acid
Sulphuric acid is a strong mineral acid with the chemical formula H2SO4. It is a pungent-smelling, colorless liquid that is soluble in water and most organic solvents.
The name derives from the Latin “sulpur” and “acidus”, meaning “sulfuric acid”. The historical name for this substance was oil of vitriol. Sulfuric acid is one of the most important industrial chemicals because it can be used to produce many other materials, such as fertilizers, detergents, plastics and styrene monomers, which are used to make polystyrene plastic.
Properties of Sulphuric Acid
Sulphuric acid is a strong corrosive acid that can dissolve metals like iron, copper and aluminium. It is also a very important industrial chemical that is used in many industries such as petroleum, fertilizers, detergents and textiles.
It is made by reacting sulphur with oxygen or air in the presence of an acid catalyst. The most common form of sulphuric acid is concentrated sulphuric acid which has a specific gravity of 1.832 and a boiling point of 98°C. It also has a high viscosity and it doesn’t react with water to form hydrogen gas which makes it useful for some industrial processes.
Sulphuric Acid : It’s Structure formation
Sulphuric Acid is a strong mineral acid with a pH of 2.2. It is the most important industrial chemical used in the production of fertilizers, detergents, and lead-acid car batteries.
The sulphuric acid molecule can exist as either an anion or a cation. The sulphate ion (SO) is the conjugate base of sulphuric acid and it has a charge of -1. The hydrogen ion (H+) is the conjugate acid of sulphuric acid and it has a charge of 1. The acidic properties are due to hydrogen ions which contribute to its acidic nature by converting metal oxides into metal hydroxides and reacting with water to form sulfuric acid in hydrolysis reactions: H+ + H2O<=> H3O+ + OH-
How is Sulphuric Acid Used in the World?
- Sulphuric acid is a strong mineral acid that has many applications in the world. In this article, we will look at how it is used in the following industries:
- Chemical industry: Sulphuric acid is used to produce fertilizers and other chemicals. It also helps to extract minerals from ores and as a preservative for oil products.
- Textile industry: Sulphuric acid is used to remove impurities from raw cotton and woolen yarns before they are spun into thread.
- Food industry: Sulphuric acid is used as a food additive to preserve canned foods, such as fruits, vegetables and soups. It also helps to bleach flour and make dough more elastic so that it can be stretched into thinner sheets for baking purposes.
- Dyeing industry: Sulphuric acid is used in the dyeing process for wool cloths and cotton fabrics, which helps with color fixation.
