give a chemical equation when B and C react with each other in presence of concentrated H2 S o4 in the major product formed and mention one of its important use
Answers
Answer:
so4 reaction with H2is to product H2So4 & use battery water
The chemical equation where B and C react with each other and forms concentrated H2 So4 as major product formed and its important use.
Explanation:
In this B and C that combines to form sulphuric acid is recognized as sulphur trioxide and water that is :
SO₃ + H₂O---> H₂SO₄
This is a part of contavt process that is the process of formation of sulphuric acid .
Contact's process
In this :
1st step : Preparation of sulphur dioxide :
S + O₂---> SO₂
2nd step :Preparation of sulphur trioxide :
SO₂ + O₂----V₂O₅----> SO₃
3rd step : Reaction of sulphur trioxide with concentrated Sulphuric acid:
SO₃ + H₂SO₄-----> H₂S₂O₇
(olleum)
4th step: Diluting this olleum:
H₂S₂O₇ + H₂O ----> H₂SO₄(Concentrated )
This sulphuric acid formed is 99% pure.
The important use of sulphuric acid is that it is dehydrating agent .
