Acid Rain (n)

Acid Rain (n). WHAT IS ACID RAIN (n) ?. Generally, rain water(n) has a pH value(n) of(prep.) 5.6 because of the carbon dioxide(n) from air(n) dissolved(v) in it( pn ). Any rainfall(n) has a pH value less than 5.6 is defined(v) as acid rain(n).

  1. Acid Rain(n)

  2. WHAT IS ACID RAIN(n)? • Generally, rain water(n) has a pH value(n) of(prep.) 5.6 because of the carbon dioxide(n) from air(n) dissolved(v) in it(pn). • Any rainfall(n) has a pH value less than5.6 is defined(v) as acid rain(n)

  3. When gas pollutants(n) e.g. sulphur dioxide, nitrogen dioxidedissolve(v) in(prep.) rain water(n), various acids(n) are formed(v). • CO2 + H2O  H2CO3 (carbonic acid)(n) • SO2 + H2O  H2SO3 (sulphorous acid) • NO2 + H2O  HNO2 (nitrous acid) + HNO3 (nitric acid)

  4. CAUSES OF ACID RAIN

  5. Formation(v) of SulphuricAcid(n)(H2SO4) 2SO2(g) + O2(g) 2SO3(g) SO3(g) + H2O(l) H2SO4(aq) Formation(v) of Nitric Acid(n)(HNO3) 2NO(g) + O2(g) 2NO2(g) 4NO2(g) + 2H2O(l) + O2(g) 4HNO3(aq)

  6. FORMATION OF ACID RAIN SO2 NOX

  7. ENVIRONMENTAL PROBLEMS(n) 1.Vegetation(n) • Wash(v) away(av) essential(adj) nutrients(n) ions from soil(n) • Poor(av) growth(v) of plants(n)

  8. 2.Aquatic Life(n) • Inflow(v) of acidic(adj) water(n) containing(v) poisonous(adj) metal ions(n) • Kill(v) the fish(n) and water plants(n)

  9. 3. Building(n) • Acid rain(n) attacks(v) the building materials(n) and causes(v) corrosion(n).
