    Understandings

    Applications and skills
    ● Rain is naturally acidic because of dissolved CO2 and has a pH of 5.6. Acid deposition has a pH
    below 5.6.
    ● Acid deposition is formed when nitrogen or sulfur oxides dissolve in water to form HNO3, HNO2,
    H2SO4, and H2SO3.
    ● Sources of the oxides of sulfur and nitrogen and the effects of acid deposition should be covered.
    ● Balancing the equations that describe the combustion of sulfur and nitrogen to their oxides and the subsequent formation of H2SO3, H2SO4, HNO2, and HNO3.
    ● Distinction between the pre-combustion and post-combustion methods of reducing sulfur oxide emissions.
    ● Deduction of acid deposition equations for acid deposition with reactive metals and carbonates.

    Inquiry questions
    8.5 How do you balance equations that describe the combustion of sulfur and nitrogen to their oxides and subsequent acids when reacted with water?
    8.5 To what extent does the chemical industry affect the environment?
