Question

18. Using the eqution below and Le Chatelier's principle, explain whether this would result in a decrease or increase in blood pH

19.

a. if [H+] in the blood increases in which direction will the equilibrium for the peceding reactions shift? Explain

b. How will this shift affect CO2 levels? Explain

c. If breathing rate controls the amount of carbon dioxide exhaled as carbon dioxide gas, will breathing rate increase or decrease in metabolic acidosis in an attempt to return blood pH to appropriate levels? Explain.

18. Certain conditions, such as asthma, lead to decreases in breathing pneumonia, emphysema, and smoke inhalation, blood. Using rate. This results in an increase in dissolved CO, in the would the equation below and Le principle, explain whether this or result in a decrease or an increase in blood pH (clinically referred to as acidosis alkalosis, respectively). H,O(l) co. g) Hzco (ag) HCOT (ag) H (ag) 19. Metabolic acidosis is the decrease in blood pH that occurs when excessive amounts of acidic substances are not removed from the blood. This can occur with prolonged physical exertion, diabetes, or restricted food intake. a) If [H in the blood increases, in which direction will the equilibrium for the preceding reactions shift? Explain. b) How will this shift affect CO, levels? Explain. c) If breathing rate controls the amount of carbon dioxide exhaled as carbon dioxide gas, will breathing rate increase or decrease in metabolic acidosis in an attempt to return blood pH to appropriate levels? Explain

Explanation / Answer

18. As the amount of dissolved carbon dioxide in blood increases, the equilibrium between water and carbon dioxide will shift to right. So more and more protons will be produced. This will increase hydrogen ion concentration and decrease pH. This results in acidosis.

Note: According to Le-Chatelier's principle, when we increase reactant concentration, the equilibrium will shift to products side. More and more reactants will be consumed and more and more products will be formed. This will increase product concentration and decrease reactant concentration. This will nullify the effect of increase in reactant concentration.
