8.5 ACID DEPOSITION
-
Problem associated
-
erosion of buildings (metals,limestone,marble)
-
-
-
Effects
-
NOx pollution
-
reacts with unreactive metals e.g : Cu,Pb
-
HNO3 reacts with rocks : CaCO3,MgCO3
-
Sources of acid rain
Nitrogen oxide
Formation
NO is very reactive,therefore 2NO + O2 :arrow_right: 2NO2
-
During electrical discharges, N2 + O2 :arrow_right: 2NO
-
N is abundantly found in atmosphere,very stable gas
