is a form of air pollution which is the cause of a lot of environmental damage now and in the past. It is formed when oxides of sulfur and nitrogen combine whith atmospheric moisture in a result it forms sulfuric (so2) and nitric (Nox) acids. What affects when it hits the surface is a lot, for example kills more than 60 ....

.... 2So3 2) So3++120 H 2So4 The second reaction takes place very quickly. Therefore, the making of So3 in the damp atmosphere is assumed to be the lead to the formation of sulfuric acid. Phase two: the aqueous phase, sulfur dioxide occurs as three species. [S {iv}] [So2{aq}]+[+1S03-] +[So32-] This process occurs by a twofold process. 1) So2 (aq) H++H S o3- 2)H so3-(aq ) h++ So32- The establishment of the equilibrium is dependent upon such things as ph. , droplet size, "sticking coefficient" for So2 o ....
