Exam 20: Acid-Base Balance

The proper ratio of the buffer pair would be 20 times more carbonic acid than sodium bicarbonate.

An acid solution has a pH above 7.0.

The most effective regulator of blood pH is

Match each term with its definition or description. -Condition that results from carbonic acid excess

A possible risk of severe,prolonged vomiting is metabolic acidosis.

When a buffer system buffers a basic solution,the weak acid donates a hydrogen ion to convert the hydroxide ion to water.

A buffer is a substance that prevents a sharp change in the pH of a solution when an acid or base is added.

The kidney also can acidify the urine by

A drop in the ratio of sodium bicarbonate to carbonic acid because of untreated diabetes can be called

When the kidneys acidify the urine,they conserve sodium bicarbonate.

Carbonic anhydrase is an enzyme found in red blood cells.

The slightly lower pH of venous blood is the result of its higher concentration of carbon dioxide.

When the carbonic acid-sodium bicarbonate buffer pair buffers an acid

The pH of a solution indicates the solution's hydrogen ion concentration.

The fluid in the body with the highest hydrogen ion concentration is

When the kidney secretes hydrogen ions,it lowers the pH of the blood.

The amino group used by the kidney to help remove hydrogen ions is contributed by a fatty acid molecule.

Proper control of the hydrogen ion concentration is important to the functioning of hemoglobin.

Match each term with its definition or description. -A solution with a pH of 7.0

Lactic acid is an example of a "fixed" acid.
