The acidity of atmospheric particles and clouds

The acidity of atmospheric particles and clouds

Many of us learned about acidity, or pH, in high school chemistry. We learned that acids like HCl could dissociate into H+ and Cl- and the activity of those H+ ions defined the acidity. In the atmosphere, the same basic definition of acidity, or pH on the molality scale, applies to aqueous phases like suspended particles and cloud droplets. Atmospheric acidity regulates what kinetic reactions are ...[Read More]
