By the Contact Process.
Elemental sulphur is burnt in air to produce sulphur dioxide.
S + O2 = SO2
The sulphur dioxide is then mixed with oxygen(air) with a vanadium catalyst.
This produces sulphur trioxide.
2SO2 + O2 == Catalyst)V_==> SO3
The sulphur trioxide is then dissolved in sulphuric acid ( made earlier) to produce oleum (fuming sulphuric acid [ very nasty stuff).
SO3 + H2SO4 = H2S2O7 (oleum)
The oleum is then dissolved into water. to produce sulphuric acid.
H2S2O7 + H2O = 2H2SO4
NB The oleum is slowly passed into a large quantity of water. NOT water into the oleum. This is because of the heat released and the oleum 'spitting' and fuming ; very dangerous.
NNB Elemental sulphur can be obtained from volcanic fumeroles, notably in Indonesia. Also Texas, USA, has 'wash out' mines, where elemental sulphur was brought to the surface.
Answer
Sulfuric acid is, fundamentally, sulfur + water. The difficulty is: sulfur insoluble in water!
In its manufacture, therefore, sulfuric acid (H2SO4) is produced from sulfur, oxygen and water via the contact process. There are two main ways: 1.
Step 1:- Sulfur is burned to produce sulfur dioxide.
= S(solid) + O2(gas) → SO2(gas) Step 2:- This is then oxidised to sulfur trioxide using oxygen in the presence of a vanadium(V) oxide catalyst.
= 2 SO2 + O2(g) → 2 SO3(g) (in presence of V2O5) Step 3.a:-The sulfur trioxide is treated with water (usually as 97-98% H2SO4 containing 2-3% water) to produce 98-99% sulfuric acid.
=SO3(g) + H2O(i.e. water) → H2SO4(liquid) Hey Presto! ----
Or, way 2.
The SO3, produced at step 2 above, can be processed in an alternative way. i.e.
Step 3.b. The SO3 can be absorbed into H2SO4 (concentrated sulfuric acid!) to produce oleum (H2S2O7)
= H2SO4(l) + SO3 → H2S2O7(l) Step 4:- Oleum can then be reacted with water to form more concentrated H2SO4.
= H2S2O7(l) + H2O → 2 H2SO4(l)
Be careful!
There are several ways to produce Sulfuric acid, but here is a list of easy ones:
Process 1:
Sulfur is burnt to produce Sulfur dioxide(SO2). Sulfur dioxide is oxidized to Sulfur trioxide(SO3) with oxygen and Vanadium(V) oxide catalyst. When it is dissolved in Water, it produces Sulfuric acid.
SO3 + H2O ----> H2SO4
Process 2:
Sulfur dioxide gas is passed through strong oxidizing liquids such as Hydrogen peroxide(H2O2) or concentrated Nitric acid(HNO3).
SO2 + H2O2 ----> H2SO4
SO2 + 2 HNO3 ----> H2SO4 + 2 NO2
Process 3:
Reacting Copper(II) sulfate with concentrated Hydrochloric acid produces Copper(II) chloride and Sulfuric acid via double displacement.
CuSO4 + 2 HCl ----> CuCl2 + H2SO4
Sulphuric acids are made when a chemical reaction occur between sulphur and water. This happens in labs when they are mixed together. It happens naturally when oxidation occurs with sulphur dioxide in water. Examples of naturally forming sulphuric acids are: Acid rain, sulphur dioxide is released mainly form burning sulphur impurities in fossil fuels; tears when cutting onions, when onions are cut they release small amounts of sulphur dioxide which can react with tears in the eye, causing irritations in the eye, so the body release more tears to prevent this irritation.
Answer:
The industrial manufacture of sulfuric acid requires several steps:
Sulphuric acid is manufactured by CONTACT PROCESS which is a three step process. These are:
Dilution of oleum gives the desired concentration of sulphuric acid.
The sulphuric acid produced by Contact process is upto 96-98% pure.
There are a number of ways. You can buy it from any local chemical store, straight from the chemical plant, or online at a science supply website, such as United Nuclear (refer the following link).
Be careful handling the acid when you get it. Sulfuric acid is a very powerful acid, and it can literally melt steel if it is exposed to it long enough.
Sulphuric acid is made of: Hydrogen, Oxygen, Sulphur
Jabber bin Hayan was the first person who introduced sulfuric acid

sulfuric acid or sulphuric acid
the chemical formula for sulfuric acid is H2SO4
Sulfuric Acid is a powerful acid and not a base.
Sulfuric acid is a reagent.
Sulfuric acid is H2SO4
No, clouds on Mars are made of ice crystals. Clouds on Venus are sulfuric acid.
sulfuric acid or sulphuric acid
Sulfuric acid is a compound since it is made of more than one element.
hydrogen, sulfuric acid
Batteries contain sulfuric acid. Sulfuric acid is corrosive to metal.
Sulfuric Acid is an oxoacid of sulfur and is made of Hydrogen, Sulfur and Oxygen. It is produced by burning sulfur in air to produce Sulfur Dioxide, and then oxidizing the Sulfur Dioxide to Sulfur Trioxide. Sulfuric Acid can then be made from Sulfur Trioxide.
The first person to burn coal inadvertently made the first sulfuric acid.
Battery acid is made of sulfuric acid, a strong acid.
No, not strictly speaking. Sulfuric acid is a mineral acid. It is made by reacting Sulfur Trioxide with water. Sulfur Trioxide IS a non-metal oxide.
