Acid deposition answers

H2CO3(aq) ⇄ H+(aq) + HCO3–(aq)so that, even in a saturated solution, the concentration of hydrogen ions can never give a pH lower than 5.6.(b) Ten times more acidic (as the pH has decreased by one unit)2. (a) 2NO(g) + O2(g) → 2NO22NO2(g) + H2O(l) → HNO3(aq) + HNO2(aq)(nitric acid can also be formed from: 4NO2(g) + O2(g) + 2H2O(l) → 4HNO3(aq) )(b) SO2(g) + H2O(l) → H2SO3(aq)
