Acid-base balance

Question 1

What are acids?

Answer 1

Electrolytes that ionize in water and release hydrogen ions

Question 2

What are bases?

Answer 2

those that release ions that combine with hydrogen ions

Question 3

What do most H+ ions originate as?

Answer 3

by-products of metabolic processes

Question 4

Examples of by products of metabolic process

Answer 4

Aerobic respiration of glucose (carbonic acid)

Anaerobic respiration of glucose (lactic acid)

Question 5

What does the digestive tract absorb?

Answer 5

some H+ ions

Question 6

What do strong acids do?

Answer 6

: ionize more completely

HCL in stomach

Question 7

What do weak acids do?

Answer 7

ionize less completely carbonic acid in the blood plasma

completely

Question 8

What do bases release?

Answer 8

Release hydroxide (OH−) or bicarbonate (HCO3−) ions;

Question 9

What happens when bases combine with H+ ions

Answer 9

the concentration of H+ ions is lowered

Question 10

What do strong bases do?

Answer 10

ionize to a great extent; example: sodium hydroxide releases OH− ions

Question 11

What do weak bases do?

Answer 11

: ionize to a lesser extent; example: sodium bicarbonate (NaHCO3) releases HCO3− ions
