ACIDS AND BASES

Question 1

also called, proton donors, substance
that release hydrogen ions in detectable
amounts
* When acids dissolve in water, it releases
H+ and anions
* The number of protons released
determines the acidity of the solution

Answer 1

Acids

Question 2

also called proton acceptors,
substances that take up hydrogen ions in
detectable amounts
u Common bases in the body: HCO3-,
Ammonia (NH3)

Answer 2

Bases

Question 3

measures the relative concentration of hydrogen ions in various
body fluids

Answer 3

pH

Question 4

ranges between 7.35
to 7.45, with the average at 7.40

Answer 4

pH of human body

Question 5

pH below 7.35

Answer 5

acidemia

Question 6

pH above 7.45

Answer 6

alkalemia

Question 7

When acids and bases mix, displacement reaction
happen to form water and salt

Answer 7

NEUTRALIZATION

Question 8

• Consists of a weak acid and a weak base that resists abrupt and large
  changes in the pH of body fluids by
  1. Releasing hydrogen ions when the pH begins to rise
  2. Binding hydrogen ions when the pH drops
• Bicarbonate buffer system

Answer 8

Buffers
