(a) NO2 is an atmospheric pollutant that reacts with rainwater to form acid rain. (i)(1) Write an equation for the reaction of NO2 with rainwater. 2NO2 + H2O → HNO2 + HNO3 (2) Hence, explain why the pH of acid rain is lower than that of rainwater. •ionises completely in water •acid has formed •HNO3 → NO3- + H+ •[H+] increases so pH decreases (ii) Identify another atmospheric pollutant that can contribute to the formation of acid rain.
