What are the uses of sulfur trioxide?
Its primary use is in the Contact Process (making Sulphuric Acid). This can be done directly by reacting Sulphur Trioxide with Water to form dilute, but highly corrosive, Sulphuric Acid: SO3(g) + H2O(l) = H2SO4(aq) It can also be achieved indirectly by adding Sulphur Trioxide to Sulphuric Acid to form Disulphuric Acid (Pyrosulphuric Acid, Fuming Sulphuric Acid or Oleum) then Reacting Disulphuric Acid with Water to Form Concentrated Sulphuric Acid: SO3(g) + H2SO4(l) = H2S207(l) H2S2O7(l) + H20(l) = 2H2SO4(l)
How is sulphuric acid prepare by lead chamber process?
In the lead chamber process, sulphur dioxide is oxidized to sulphur trioxide using atmospheric oxygen in the presence of a vanadium oxide catalyst. The sulphur trioxide is then absorbed in water to form sulphuric acid. The lead chamber process gets its name from the large lead-lined chambers used in the process to contain the reaction.
What is compound form when sulfur trioxide dissolved in concentrated sulphuric acid?
The product is Disulphuric acid. Its other name are Pyrosulfuric acid, Fuming sulphuric acid and Oleum. Its formula is H2S2O7 . Its salts are called Disulphates and contain the S2O7-2 anions. It decomposes in water to produce Sulphuric acid.Sulphuric acid + Sulphur trioxide ----> Disulphuric acidH2SO4 + SO3 ----> H2S2O7 (already balanced equation)
How does sulphuric acid get in to rain?
Sulphur Dioxide is a a by-product of (mainly) powerstations that burn fossil fuels to produce the steam ofr the turbines. Sulphur Dioxide combines with water in the atmosphere to produce Sulphuric acid - which falls as 'acid rain. The chemical process is... SO2 + OH → HOSO2 - which is followed by... HOSO2 + O2 → HO2 + SO3 In the presence of water, sulphur trioxide (SO3) is converted rapidly to sulphuric acid... SO3 + H2O → H2SO4
What is formed whem Sulfur dioxide reacts with water?
Sulphurous acid is formed when sulphur dioxide dissolves in water. Sulphuric acid is formed when sulphur trioxide dissolves in water. Over time, sulphurous acid will oxidize to sulphuric. SO2 + H20 -> H2SO3 (sulphurous acid) SO3 + H20 -> H2SO4 (sulphuric acid)
Why are scrubbers used to reduce sulphur dioxide in the atmosphere?
Sulphur scrubbers on coal fired power plants use a multistage system:The stack gasses containing sulphur dioxide gas are passed over a catalytic bed with the addition of extra oxygen to convert the sulphur dioxide gas to sulphur trioxide gas.The stack gasses now containing sulphur trioxide gas are passed through a chamber containing water spray and the sulphur trioxide gas dissolves in the water producing highly concentrated sulphuric acid, which precipitates out of the stack gasses as a liquid.The concentrated sulphuric acid is concentrated more producing "Oleum" a very oily industrial grade of sulphuric acid. "Oleum" can often be sold to chemical companies with no further processing.If the market for "Oleum" does not offer enough demand, then it can be processed through additional steps to extract the dry sulphur as yellow crystals called "flowers of sulphur".
What does sulfuric acid combine with particles to form?
Sulphur is first oxidized to sulphur trioxide(SO3) and then it is passed through water to form sulphuric acid. To know further about the manufacturing of sulphuric acid, follow the link below.

Why is acid rain acidic?
All plants and animals must have sulphur. Coal and oil are made from old plants and animals that lived millions of years ago. They contain sulphur. Refineries can remove most of the sulphur from most of the oil turned into fuel oil or gasoline. Refineries, factories and power plants can remove the sulphur dioxide from their smokestacks. Frequently they do not. When they do not, the sulphur dioxide turns into sulphur trioxide. The Sulphur trioxide then when the sulphur trioxide runs into a cloud or a drop of water, it turns into sulphuric acid. When it falls to earth, it falls as acid rain. Acid rain is sulphuric acid falling to earth. In North Florida the rain accompanying the first cold front of the fall changed the pH of a swimming pool from 8 to 4. That indicates the amount of acid in the air over the Midwest and Midsouth of the United States. Right now technology exists to rid smokestacks of sulphuric acid.
The reaction between sulfur trioxide and water is called?
Dissolution of SO3 in water. to form sulphuric Acid. Industrially, sulphur trioxide is dissolved in sulphuric acid to form oleum. Oleum ( fuming sulphuric acid) is seriously nasty stuff. SO3 + H2SO4 = H2S2O7 The oleum is then slowly dissolved in water to form sulphuric acid of the given molarity(strength). H2S2O7 + H2O = 2H2SO4 It is done this way in order to prevent 'spitting and fuming'. added to which you form twice a mush sulphuric acid.

How is sulphuric acid produced?
Sulphuric acid is produced by two major process industrially. 1. The contact and absorption process a.single contact single absorption process. b.double contact double absorption process. 2.The chamber process In the contact process, sulphur is burned in a furnace to produce sulphur dioxide which is then converted in to sulphur trioxide using catalyst converter. The catalyst is normally vanadium pentoxide. This sulphur trioxide gets absorbed in a absorption tower when it comes in contact with x% of sulphuric acid. x% contains some y% of water,this absorbs the sulphur trioxide to produce sulphuric acid. The equations are: Combustion process: S + O2 ---> SO2 (over V2O5) Conversion process: SO2 + 1/2 O2 ---> SO3 Absorption process: SO3 + H2O ---> H2SO4
What are the Ways to convert dilute sulphuric acid to concentrated sulphuric acid?
One way to convert dilute sulphuric acid to concentrated sulphuric acid is through a process called evaporation. In this method, the dilute acid is heated to evaporate the water content, leaving behind the concentrated acid. Another method involves adding concentrated sulphuric acid to the dilute solution until the desired concentration is achieved.
