Chemistry Question on Environmental Chemistry
Sulphur dioxide is one of the components of polluted air. SO2 is also a major contributor to acid rain. The correct and complete reaction to represent acid rain caused by SO2 is
A
2SO2 + O2 -> 2SO3
B
SO2 + O3 -> SO3 + O2
C
SO2 + H2O2 -> H2SO4
D
2SO2 + O2 + 2H2O -> 2H2SO4
Answer
2SO2 + O2 + 2H2O -> 2H2SO4
Explanation
Solution
The correct answer is (D) : 2SO2 + O2 + 2H2O → 2H2SO4
Acid rain occurs due to increased concentration of oxides of sulphur and Nitrogen.
The correct and complete reaction to represent acid rain caused by SO2 is
2SO2 + O2 + 2H2O → 2H2SO4
