Defination :-
The rain having PH less than 5.6 Rain.
The rain having PH less than 5.6 Rain.
Explanation: -
Normal rain water is saturated with carbon dioxide. It has PH of 5.6 however ; the acidity of rain greatly increases in polluted areas during thunderstorm.Sulphur dioxide from power plants using fossil fuels and nitrogen oxides from exhaust fumes of automobiles dissolve in rain water producing acids.
2SO2 + O2 → 2SO3
Therefore, during thunderstorms, the PH of rain water can be much lower because of sulphuric acid and nitric acids formed by lightening .This rain may have PH as low as 2.1. This value is lower than the PH of vinegar or lemon juice.
Sulphuric acid eats away metals to formvwater soluble salts and hydrogen
Fe + H2SO4 →FeSO4 + H2
Marble buildings and statues are slowly eroded by acid rain.
CaCO3 + H2SO4 → CaSO4 + H2O + CO2
Acid rain also kills fish, and destroys trees.Lakes and river may become too acidic for living things to survive.
