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

    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 alkalosis conditions?

     

     

     

    b. What happens to the [H3O+] (aq) under alkalosis conditions?

     

     

     

    c. In which direction does the equilibrium shift in equation 2?

     

     

     

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

     

     

     

    e. In which direction does the equilibrium shift in equation 1?

     

     

     

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

     

     

     

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