In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together....
Full size image To further evaluate the role of SO2 and Mn2+, chamber experiments were carried out with different concentrations of Mn2+ and SO2 under similar relative humidity (RH) and NH3 conditions. As shown in Fig. 1b, the measured sulfate formation rates varied linearly with the concentra...

In the Knudsen cell, reactant gas molecules can be lost in deliquesced sea salt aerosol with dissolved oxidants such as ozone and H202 to form S(VI) species [Luria and Sievering, through the small exit aperture or by uptake by the sample. A 1991; Sievering et al., 1991, 1992, 1995;...
Full size image As shown in Fig.4b, we find in this air parcel model that reactions (R1) and (R2) are sufficiently fast for complete conversion of SO2to sulfate at pH > 5.5, with a maximum contribution from reaction (R1) at pH 5.5. At higher pH, the faster kinetics of reaction...
