Abstract
Different mechanisms of formation of sulfuric acid in nebulous drops a re considered. Equations for calculation of the rate of acidification of a drop according to different mechanisms are derived, Relative sign ificance of three main routes are compared: noncatalytic chain oxidati on of sulfite by oxygen, stoichiometric oxidation of sulfite by hydrog en peroxide; and oxidation of sulfite by oxygen catalyzed by Mn(II) an d Fe(III) ions. A key role of the catalytic oxidation of sulfite in th e formation of acidic rains is shown. Based on the analysis performed, a method for decreasing the acidity of rains is suggested.
