What is the definition of sulfuric acid in chemistry?
Definition of sulfuric acid : a heavy corrosive oily dibasic strong acid H2SO4 that is colorless when pure and is a vigorous oxidizing and dehydrating agent.
What is the process of sulfuric acid?
Sulfuric acid is prepared industrially by the reaction of water with sulfur trioxide (see sulfur oxide), which in turn is made by chemical combination of sulfur dioxide and oxygen either by the contact process or the chamber process.
What is in sulphuric acid?
Sulfuric acid (American spelling and the preferred IUPAC name) or sulphuric acid (Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with the molecular formula H 2SO 4.
What are the steps involved in the manufacture of sulphuric acid by contact process?
The manufacture of sulphuric acid using the contact process involves four steps….These include;
- Extraction of sulphur.
- Preparation of sulphur dioxide.
- Conversion of sulphur dioxide to sulphur trioxide.
- Conversion of sulphur trioxide to sulphuric acid.
What type of acid is sulfuric acid?
sulfur oxoacid
Sulfuric acid is a sulfur oxoacid that consists of two oxo and two hydroxy groups joined covalently to a central sulfur atom. It has a role as a catalyst. It is a conjugate acid of a hydrogensulfate. Sulfuric acid, spent appears as a black oily liquid.
What is short form of sulphuric acid?
Acronym. Definition. H2SO4. Sulfuric Acid (chemistry)
What is work of Sulphuric acid?
Uses of Sulphuric Acid Sulphuric acid is highly acidic. Therefore, it is used in the cleaning of metals, removal of impurities from oil, manufacturing of chemicals – nitric acid, hydrochloric acid, synthesis of dye, drugs, detergents, explosives, etc.
What is the PH of Sulphuric acid?
What Is The pH Value Of Sulphuric Acid?
| Sulphuric acid | 1 mM | 100 mM |
|---|---|---|
| 2.75 | 1.01 |
What are the steps involved in the manufacture of Sulphuric acid by contact process mention the Favourable conditions for obtaining maximum yield?
Manufacture of H2SO4 by contact process involves three steps:
- Burning of sulphur in air to generate SO2.
- Conversion of SO2 to SO3 by oxidation with air in the presence of V2O5 as catalyst.
- Absorption of SO3 in H2SO4 to obtain oleum H2S2O7. A flow diagram for the manufacture of H2SO4 is given below:
How is Sulphuric acid prepared by lead chamber process?
In this process, a mixture of SO2, air, steam and oxides of nitrogen is passed through a series of lead chambers. SO2 is oxidized to SO3 by oxides of nitrogen which function as a catalyst. Sulfur trioxide so formed then reacts with steam (H2O) to form sulfuric acid.
What are the properties of Sulphuric acid?
Physical Properties of Sulphuric Acid
- Sulfuric acid is a thick, colourless and an oily fluid.
- It has a specific gravity of 1.84 at 298 K.
- The boiling point of the acid is 611 K.
- This strong chemical reacts with water vigorously releasing quite a lot of heat.
What is the PH of sulphuric acid?
How do you write sulfuric acid?
The formula for sulfuric acid is H2SO4.
What Colour is sulphuric acid?
colorless
Sulfuric acid is a colorless oily liquid.
What are the steps of contact process?
The Contact Process: Step 1: Make sulfur dioxide. Step 2: Convert sulfur dioxide into sulfur trioxide (the reversible reaction at the heart of the process) Step 3: Convert sulfur trioxide into concentrated sulfuric acid.
How is sulphuric acid prepared in the laboratory?
Sulphuric acid is produced from sulphur. In the presence of air, sulphur dioxide is first obtained by burning the molten sulphur. In the presence of a catalyst for vanadium pentoxide, sulphur dioxide is then converted to sulphur trioxide.
Why it is called lead chamber process?
chamber process, also called Lead-chamber Process, method of producing sulfuric acid by oxidizing sulfur dioxide with moist air, using gaseous nitrogen oxides as catalysts, the reaction taking place primarily in a series of large, boxlike chambers of sheet lead.
Why is sulfuric acid important?
In modern industry, sulfuric acid is an important commodity chemical, and is used primarily for the production of phosphoric acid. It is also good for removing oxidation from iron and steel, so it is used in large quantities by metal manufacturers. Sulfuric acid is a very dangerous chemical.
