    1. Explain how respiration (lungs) helps maintain blood serum pH during acidosis.

    Write the two equilibrium equations responsible for maintaining pH

    Equation 1:      Show CO2 dissolving in water.              

     

     

    Equation 2:    Show the dissociation of carbonic acid in water.

     

     

     

    a.      What happens to the pH of the blood under acidosis conditions?

     

     

    b.     What happens to the concentration of H3O+ (aq) under acidosis conditions?

     

     

    c.      In which direction does the rate increase in equation 2?

     

     

    d.     What happens to the concentration of H2CO3 (aq) as a result of the shift?

     

     

    e.      In which direction does the rate increase in equation 1?

     

     

    f.      What happens to the concentration of CO2 (g) as a result of the shift?

     

     

    g.     How do the lungs compensate for the changes in [CO2]?
