what materials does acid deposition impact?
CaCO3 and reactive metals
acid deposition impact on CaCO3?
CaCO3 + H2SO4 –> CaSO4 + CO2 + H2O (causes material expansion)
CaCO3 + 2HNO3 –> Ca(NO3)2 + CO2 + H2O (causes errosion)
acid deposition impact on reactive metals?
Fe + H2SO4 –> FeSO4 + H2 (causes errosion such as rusting)
production of H2SO3
- S + O –> SO2
- SO2 + H2O –> H2SO3
production of H2SO4
- S + O –> SO2
- 2SO2 + O2 –> 2SO3
- SO3 + H2O –> H2SO4
production of HNO2/HNO3
- N2 + O2 –> 2NO
- 2NO + O2 –> 2NO2
- 2NO2 + H2O –> HNO2 + HNO3
or - 4NO2 + O2 + H2O –> 4HNO3
