Acid rain negatively affects plants by A. reducing the photosynthetic rate in the leaves B. burning the leaves and bark. C. leaching cations that the plant needs from the soil D. leaching anions from the soil that the plant needs Solution Acid rain is a mixture of inorganic acids like H2SO4 and HNO3. These acids are from upon the reaction of pollutant like NOx and SO2 with water oxygen and other components present in the air. Both the acids are strong acid and it is the property of strong acid to dissociate into proton and Sulphate or Nitrate ions. In the soil cation, such as Potassium, calcium and magnesium are present, in their mineral forms, which are exchange with proton in acidic condition. Once cation is exchanged they leach into the soil are no more available for the plants..
