    About the Lecture

    The lecture Buffer: Definition & Titration Curves by Thad Wilson, PhD is from the course Acid-Base Balance.


    Included Quiz Questions

    1. A substance capable of releasing (or binding to) hydrogen ions
    2. A substance present in the blood
    3. A protein in the blood
    4. A substance that binds to hydrogen and does not release it
    5. A substance that disassociates in blood
    1. The pH at which the substance is 50% bound to H+ (H2CO3) and 50% free (HCO3-)
    2. The pH of the blood
    3. The amount of carbonic acid in the blood
    4. The amount of bicarbonate in the blood
    5. The amount of CO2 in the blood
    1. We add the pK of bicarbonate/carbonic acid to the log of the ratio between the patient's serum bicarbonate over serum PCO2x0.03 (CO2's solubility coefficient)
    2. We calculate the log of the ratio between the patient's serum bicarbonate over serum PCO2x0.03 (CO2's solubility coefficient)
    3. We calculate the log of the ratio between the patient's serum PCO2x0.03 (CO2's solubility coefficient) over serum bicarbonate
    4. We add the pK of bicarbonate/carbonic acid to the log of the ratio between the patient's serum PCO2x0.03 (CO2's solubility coefficient) over serum bicarbonate
    5. We add the pH of the blood to the pK of bicarbonate/carbonic acid
