Exam 20: Acid-Base Balance

The carbon dioxide that is exhaled reduces the amount of carbonic acid in the blood.

To raise the pH of the blood,the kidneys lower the hydrogen ion concentration of the urine.

A common buffer pair is sodium bicarbonate and carbonic acid.

The pH of a solution is based on the exponent of the hydrogen ion concentration.

A solution with a pH of 9.0 would

Match each term with its definition or description. -A substance that prevents a sharp change in pH

Alkalosis occurs when the

A "fixed" acid does not break down to form a gas.

An alkaline solution has a pH greater than 7.0.

Effective functioning of which of the following depends on the regulation of the hydrogen ion concentration?

As the pH value of a solution goes up,the hydrogen ion concentration goes up.

In alkalosis,the hydrogen ion concentration of the blood rises.

The part of the nephron that secretes hydrogen ions into the urine is the

If the sodium bicarbonate-carbonic acid buffer pair was to buffer a solution of HCl,more carbonic acid would be formed.

In the kidney,ammonia is exchanged for sodium bicarbonate.

What specifically is the cause of respiratory acidosis? What diseases or conditions can bring this about?

Gastric juice is the most acidic substance in the body.

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

When the ratio of the buffer pair falls below what it should be,uncompensated metabolic acidosis can occur.

The kidney is the most effective regulator of body pH.
