Sulphuric Acid in One Shot | Explained by IITian | Jee Mains | Advanced | NEET | AIIMS

Sulphuric acid, H2SO4 is an odorless, colorless, oily liquid that is extremely corrosive It was at first called Oil of Vitriol. 1. It occurs in both combined and free state. 2. It is framed close to the sulfide beds. 3. In the joined frame, it happens as metallic sulfates (salts in minerals). Manufacture of Sulphuric Acid Commercially, Sulphuric Acid can be prepared by two techniques that are as follows: 1. Lead chamber process 2. Contact process Contact Process The contact process includes three steps: Step–I: Production of Sulphur Dioxide: This can be made by smoldering sulfur or sulfide ores, for example, iron pyrites in abundance of air.  S (Sulphur) + O2 (Oxygen) + Δ (Heating)  →  SO2 (Sulphur dioxide) 4FeS (Iron pyrites) + 7O2 (Oxygen) + Δ (heating) →  2Fe2O3 (Ferric Oxide) + 4SO2(Sulphur dioxide) Step -II: Formation of Sulphur Trioxide: Sulphur dioxide is oxidized to sulphur trioxide with atmospheric oxygen within the sight of V2O5 as a catalyst. 2SO2 (Sulphur dioxide) + O2 (Oxygen) + V2O5 (Catalyst) → SO3 (Sulphurtriioxide) Step -III Conversion of Sulphur Trioxide into Sulphuric Acid:The sulfur trioxide shaped in the second step is broken up in 98% sulphuric acid to give pyrosulphuric acid or oleum. Oleum is then diluted or weakened with water to give sulphuric acid of the concentration that is required.  SO3 (Sulphur trioxide) +  H2SO4 (Sulphuric acid-98%)  →    H2S2O7 (Pyrosulphuric acid -Oleum) H2S2O7 (Pyrosulphuric acid -Oleum) +  H2O (Dilution )  →   2H2SO4(Sulphuric acid) Lead Chamber Process Lead Chamber process is one of the sulphuric acid manufacturing strategies which give just around 50-60 B grade acids. The fundamental standard of the procedure is that the wet SO2 (Sulfur Dioxide) in the nearness of nitrogenous oxides (dynamic impetus) is oxidized to sulfur trioxide with the oxygen exhibit in air. Sulfur trioxide is made to react with water to create sulphuric acid. The reactions would resemble beneath: 2SO2 + O2 → 2SO3 SO3 + H2O → H2SO4​ Sulphuric Acid is a very strong dibasic acid. It ionizes in two stages in aqueous solution: Step 1:           H2SO4(aq) + H2O(I)  →  H3O+(aq) + HSO4-(aq);           Ka1 = very large (Ka1 greater than 10)Step 2:           HSO4(aq) + H2O(I) →  H3O+(aq) + SO42-(aq);           Ka2 = 1.2 x 10-2 • The acid neutralizes alkalis and structures two arrangement of salts bisulphates and sulfates. Example: Concentrated sulphuric acid reacts with sodium hydroxide and structures sodium bisulphate and sodium sulfate. H2SO4 (Conc.Sulphuric acid) + 2NaOH (Sodium hydroxide)→  2NaHSO4 (Sodium bisulphate) + H2O (Water)H2SO4 (Conc.Sulphuric acid)  + 2NaOH (Sodium hydroxide) →  Na2SO4 (Sodium sulphate) + 2H2O (Water) • Sulphuric acid is utilized as a part of the preparation of more volatile acids from their comparing salts as it is less volatile. • Concentrated Sulphuric acid liberates hydrogen chloride from sodium chloride and hydrogen fluoride from calcium fluoride. CaF2 (Calcium fluoride)+ H2SO4 (Conc. Sulphuric acid) →  CaSO4(Calcium sulphate)  +  2HF (Hydrogen floride) • Concentrated Sulphuric acid is an intense dehydrating agent. This property is utilized as a part of drying many wet gasses that don't react with the acid. • Sulphuric acid additionally expels water from natural mixes like starches. Example: • It burns glucose, sugar, and starch to carbon. C12H22O11(Cane sugar) + (H2SO4)  →  12C (Carbon)  +  11H2O (Water) • Hot concentrated Sulphuric acid is a decent oxidizing agent. It oxidizes both nonmetals as well as metals and itself gets reduced to sulfur dioxide. And many more reactions has been discussed in details.
