5.12 understand that nitrogen oxides and sulfur dioxide are pollutant gases which contribute to acid rain, and describe the problems caused by acid rain

NO and SO2 are given off into the atmosphere by some industrial processes.
When they are in the atmosphere they react with rain water to create H+ ions.
When the rain falls the acid can corrode rocks and buildings. Acid can also alter the PH in soil or rivers which can effect an ecosystem.
Also acid rain corrodes limestone, which damages buildings and stuff.

    1. I think the H+ ions are the acid part of the acids. Sulphur trioxide and nitrogen dioxide dissolve in water to form sulphuric acid and nitric acid, of which they are H2SO4 and HNO3. The hydrogen ions are the reason they are an acid.
