Vedclass · Answer

(B) Acid rain is primarily caused by the emission of acidic oxides such as sulphur dioxide $(SO_2)$,nitrogen oxides $(NO_x)$,and carbon dioxide $(CO_2)$ into the atmosphere.These gases are released mainly through the burning of fossil fuels,industrial processes,and vehicular emissions.When these gases react with water vapor in the atmosphere,they form acids like sulphuric acid $(H_2SO_4)$,nitric acid $(HNO_3)$,and carbonic acid $(H_2CO_3)$.These acids then dissolve in rainwater,lowering its $pH$ and resulting in acid rain.
