Here are some typical questions you will find: QUESTION 6 Acid rain has a pH that is low enough to cause environmental damage. (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.
