Exam 44: Acid-Base Balance

For the body to maintain an acid-base balance, which of the following is (are) necessary?

The pH of the blood is maintained at approximately:

Hyperventilation can result in loss of consciousness because:

On the pH scale, as the value moves from 1 toward 7, the concentration of hydrogen ions increases.

Stomach acid is the most alkaline substance in the body.

Distilled water (pure water) contains equal amounts of hydrogen and hydroxide ions.

On the pH scale, as the value moves from 1 toward 7, the concentration of hydrogen ions decreases.

An increase in ammonium ion excretion occurs when there is an increase in blood pH.

A solution with a pH of 7 would have no hydrogen ions in solution.

On the pH scale, as the value moves from 14 toward 7, the concentration of hydroxide ions decreases.

Kidney tubule base bicarbonate reabsorption and hydrogen ion excretion both tend to alkalinize the blood by acidifying the urine.

For the bicarbonate buffer system to function, both the absolute amount and the ratio of the components must remain constant.

The more an acid dissociates, the stronger the acid is said to be.

A solution with pH of 7 would contain _____ times the number of hydrogen ions as a solution with a pH of 8.

Which of the following is(are) classified as an acid-forming food?

Potassium salts of hemoglobin are important in buffering _____ acid.

If NaOH were buffered by H-HCO₃, what would occur?

Why does arterial blood have a lower hydrogen ion concentration than venous blood?

A diet that is very high in protein or very high in fruits and vegetables would tax the body's ability to maintain acid-base balance.

Citrus fruits are mainly acid forming when metabolized.
