A person who overdoses on antacids may neutralize too much stomach acid, which causes an imbalance in the bicarbonate equilibrium in die Wood. CO 2 ( g ) + 2H 2 O ( l ) ⇌ H 3 O + ( a q ) + HCO 3 - ( a q ) a. How does blood pH change when this occurs? b. In which direction will the bicarbonate equilibrium shift during an Alka-Seltzer ® overdose? c. What is this condition called? d. To treat severe forms of this condition, patients are administered NH 4 C1, which acts as a weak acid. How does this restore the bicarbonate equilibrium? e. In which direction will the bicarbonate equilibrium shift as the pH returns to normal?
