- Consider the equilibrium shown below; indicating the buffering system in the blood circulation. CO, + H,0 [H,CO3] HCO3¯+H* When a patient is choking, would this lead to an alkalosis or an acidosis situation? Explain.Buffer systems can absorb hydrogen ions from the blood to increase pH into homeostatic range (pH: 7.35 to 7.45)During what condition would buffer systems do this?Calcium carbonate (CaCO₃(s)) is an important building material (limestone) and a quick cure for acid indigestion (TUMS). Ksp = 8.7x10⁻⁹ for CaCO₃(s). What, if any, is the effect of lowering the pH (as occurs in acid rain and acid indigestion) on the solubility of CaCO₃(s). (hint: use Le Chatelier's principle) A) there is no effect from lowering pH on CaCO₃(s) solubility B) lowering pH increases the CaCO₃(s) solubility C) additional information is required to determine the outcome D) lowering the pH lowers the solubility
- Metabolic alkalosis refers to a process whereupon decreased hydrogen ion, or increased bicarbonate, concentrations occur in the body, and the blood pH becomes too basic. Answer the following questions: How does the body regain its acid-base equilibria/balance? What happens when that balance does not happen? Will a buffer system still work under these conditions?Three systems of the body help regulate acid/base balance - buffer system, respiratory system and renal system.

- During the treatment for COVID-19, one complication includes an increase of CO2 in the lungs. This buildup of CO2 can result in a serious condition called respiratory acidosis if the level of H+ significantly changes. If the pH drops by 1 unit, what has happened to the H+ concentration?The glass electrode used in commercial pH meters gives an electrical response proportional to the concentration of hydrogen ion. To convert these responses to a pH reading, the electrode must be calibrated against standard solutions of known H+ concentration.
