Pure water,with a pH of 7,is neither acid nor base because it contains neither hydrogen ions nor hydroxide ions.
(79) VerifiedFalse
Explain how the buffer system functions to buffer a strong base.

Answered by Examlex AI CopilotA buffer system functions to maintain a stable pH level by resisting changes in acidity or alkalinity when a strong base is added. In the case of a strong base being added to a buffer solution, the buffer system will work to neutralize the base without causing a significant change in pH.
The buffer system consists of a weak acid and its conjugate base, or a weak base and its conjugate acid. When a strong base is added to the buffer solution, the weak acid in the buffer system will react with the base to form its conjugate base and water. This reaction helps to neutralize the added base and prevent a drastic increase in pH.
Similarly, if a strong base is added to a buffer solution containing a weak base and its conjugate acid, the weak base will react with the added base to form its conjugate acid and hydroxide ions. This reaction also helps to neutralize the added base and maintain the pH of the solution.
Overall, the buffer system functions to resist changes in pH by utilizing the equilibrium between the weak acid and its conjugate base, or the weak base and its conjugate acid, to neutralize the effects of added strong bases and acids. This allows the buffer solution to maintain a relatively constant pH even when strong bases are introduced.
When the kidneys work to raise the pH of the blood,the blood becomes more alkaline and the urine becomes more acidic.
(82) What is uncompensated metabolic acidosis? How does it become compensated metabolic acidosis?
(78) A solution with a pH of 2 has 1000 times more hydrogen ions than a solution with a pH of 5.
(73) A prolonged period of gastric suctioning would have the same effect on the blood pH as a prolonged period of uncontrolled diabetes.
(71) If a base were added to the buffer pair H2CO3-NaHCO3,the concentration of H2CO3 would drop.
(79) Suppose the 20:1 ratio needed by the H2CO3-NaHCO3 buffer pair is disrupted and the concentration of NaHCO3 in the blood needs to be lowered.What mechanism could be used to accomplish this?
(70) Because the functioning of proteins such as enzymes and hemoglobin depends on a proper pH level,pH must be regulated closely.
(80) The amount of carbonic acid is lower in the pulmonary vein than it is in the pulmonary artery.
