High acidity in rain fall cloud droplets and fog droplets in areas influenced by anthropogenic sources of SO/sub 2/ (g) and NO /SUB x/ (g) has been attributed to the formation of both H/sub 2/SO/sub 4/ and HNO/sub 3/. It has been suggested based on the analysis of field data, that rapid conversion of SO/sub 2/(g) to sulfate must occure in cloud or fog droplets. Data on the conversion of SO/sub 2/(g) to sulfate in water droplets is largely confined to the results of laboratory studies. Hegg and Hobbs have reported on the production of sulfate in wave clouds based on the measurement of particulate matter sulfate concentrations before and after passage of an air mass through the cloud. Because of major uncertainties in the measurement of the residence (and hence reaction) time of the air mass in the cloud, their results have large uncertainties. However, the oxidation rate in the more acidic clouds (pH of cloud droplets<5) was 20 + or - 33% SO/sub 2/(g) hr/sup -1/
