8.3 Acid Deposition

Question 1

Marks: 1

The pH of clean rain water is around 5.5. Which substance is responsible for this?

  • Methane

  • Carbon dioxide

  • Nitrogen oxides

  • Sulfur dioxide

Choose your answer
  

Question 2

Marks: 1

Which statement is not true about the increasing levels of atmospheric carbon dioxide?

CO2 (g) + H2O (l) ⇌  H+ (aq) + HCO3- (aq)

HCO3- (aq) ⇌ H+ (aq) + CO32- (aq)

  • The concentration of HCO3- increases in water bodies

  • The concentration of H+ increases in water bodies

  • The pH of lakes and oceans falls as the CO2 levels increase

  • The increasing concentration of CO32- enables marine organisms to build thicker shells
