Q. 1000 L of air at STP was dissolved in water and it required 2.5×10−5 moles of KMnO4 for complete reaction with the pollutant SO2. Thus, the SO2 content in air is:
- 1.4 ppm
- 14 ppm
- 2.8 ppm
- 6.25 ppm
Q. SO2, as a pollutant can be controlled by:
(I) Using solar energy, nuclear energy, hydroelectric energy.
(II) Using low-sulphur fuels, natural gas.
(III) The desulphurisation of high-sulphur coal and oil before burning by FGD (Fuel-gas desulphurisation).
(IV) Using water under high pressure.
The correct methods are:
(I) Using solar energy, nuclear energy, hydroelectric energy.
(II) Using low-sulphur fuels, natural gas.
(III) The desulphurisation of high-sulphur coal and oil before burning by FGD (Fuel-gas desulphurisation).
(IV) Using water under high pressure.
