the chemistry of acid rain from sulphur oxides complex because it can _____________
be deposited in various forms:
1. can react to form H2SO3
2. can be oxidized to SO3(g) and precipitate as H2SO4(aq)
3. can precipitate as wet deposition or assoc. within particulate matter (deposits as sulfite or sulphate ions)
what is the oxidation of SO2?
what is the homogenous gas phase oxidation?
what is the homogenous water phase reaction?
what are the details of mechanism of oxidation of SO2 in clouds or raindrops still uncertain:
what is the cycle of gas phase oxidation and water-phase oxidation?
what is the gibbs free energy of phases?
what is adsorption and distribution equilibria?
what is the graph of a water droplet?
what are SO2 emission sources?
what is the heterogenous oxidation of SO2 on particles?
what is the oxidation and deposition of SOx?
what are the effect of acidic emissions?
due to either effects of:
-1. effects of gaseous pollutants
-2. effects of lowered pH on water soil, or other materials
