1 1 ATM 6, Lecture #14 Cort Anastasio Atmospheric Science Program University of California - Davis Acid Rain Part I: Background and Formation and Deposition of Acids 2 Background (I): Acids • What is an acid? – Several definitions – Ours: acid =______________________________________________ ________________________________________________________ • What are some common atmospheric acids? – Sulfuric: H 2 SO 4 (aq) 2 H + + SO 4 2– – Nitric: HNO 3 (aq) H + + NO 3 – Hydrochloric: HCl(aq) H + + Cl – Carboxylic (organic) acids, such as formic (HCOOH) and acetic (CH 3 COOH) • HCOOH(aq) H + + HCOO •CH 3 COOH(aq) H + + CH 3 COO – Note: aq = aqueous, i.e., compound dissolved in water.

2 3 Background (II): Bases • What is a base? – Ammonia: •NH 3 (aq) + H 2 O(liquid) NH 4 + + OH •NH 3 is dominant atmospheric base – Carbonates from soil dust, such as calcium carbonate (CaCO 3 ) •C aCO 3 (solid) Ca 2+ + CO 3 2– , followed by •CO 3 2– + H + HCO 3 – Compound that can remove H + (or release OH , hydroxide ions) –H + and OH are inextricably linked through water •H + + OH H 2 O •[H + ] × [OH ] = 10 –14 M 2 ; This value is constant in water.
