BUFFER NOTES

Question 1

dissociation constant of
water (Kw)

Answer 1

1x10-14 at 25°C

Question 2

also known as the
self-ionization constant or ion product of water, is denoted by Kw

Answer 2

dissociation constant of
water (Kw)

Question 3

It is a measure of the ability of water to
dissociate into hydrogen ions (H+) and hydroxide ions
(OH-).

Answer 3

dissociation constant of
water (Kw)

Question 4

is a solution that resists changes in pH
when small amounts of acid or base are added.

Answer 4

buffer solution

Question 5

is composed of a weak acid and its
conjugate base, or a weak base and its conjugate acid.

Answer 5

buffer solution

Question 6

helps to neutralize excess
hydrogen (H+) or hydroxide ions (OH-), maintaining a relatively stable pH.

Answer 6

conjugate base or acid

Question 7

this regulates blood pH

Answer 7

Bicarbonate buffer system (H2CO3/HCO3-)

Question 8

this regulates pH in kidneys and other tissues

Answer 8

Phosphate buffer system (H2PO4 -/HPO42-)

Question 9

proteins like hemoglobin and albumin help regulate pH in blood and other tissues

Answer 9

Protein buffer system
