Document Summary

Acid rain: natural rain is acidic due to dissolved co2, co2(g) + h2o(aq) h2co3(aq, h2co3 is a weak diprotic acid, h2co3(aq) h+(aq) + hco3. Predominant acids are hno3 and h2so4: primary pollutants are so2 and no, not all (cid:862)a(cid:272)id(cid:863) on earth is the result of rainfall. Large amounts of nh3 (weak base) result in deposition of nh4. +, which is then oxidized to no3: nh4+ + 3h2o no3- + 10h+ + 8e, still end up with acid being produced in the soil. Limestone is a carbonate - carbonate is basic: limestone is found in southern ontario - where we are. Soil/lakes containing limestone neutralize the acidity: caco3 (s) + h+(aq) ca2+(aq) + hco3, hco3. (aq: these reactions will go on quite efficiently. Liming; addition of ca(oh)2: addition of phosphate ion, po4, denitrification converts no3. To n2; uses large quantities of h: 2 no3.
