How do buffers help organisms whose bodies require near neutral pH (pH of 7) maintain even when they ingest acidic and basic substances? A buffer solution has a fixed pH value that does not change at all upon the addition of acid or base. Buffers absorb the free hydrogen ions (H+) and hydroxide ions (OH-) that result from chemical reactions. Buffers rely on the difference in electronegativity between oxygen and hydrogen molecules in water. Nucleotides contain each of the following components except 3' OH group, phosphate group, carbon ring, sugar, water molecule.

The function of a buffer is to a) bring the pH of a solution to neutral. b) speed up chemical reactions within a cell. c) interact with phospholipid molecules to form a cell membrane. d) stabilize the pH of a solution. e) provide energy for synthesis of ATP.
What is the capacity of a buffer? How do the following buffers differ in capacity? How do they differ in pH? $0.01 M$ acetic acid/0.01 $M$ sodium acetate $0.1 \mathrm{M}$ acetic acid/0.1 $\mathrm{M}$ sodium acetate $1.0 \mathrm{M}$ acetic acid/ $1.0 \mathrm{M}$ sodium acetate Which of the following can be classified as buffer solutions? a. $0.25 M \mathrm{HBr}+0.25 \mathrm{M} \mathrm{HOBr}$ b. $0.15 M \mathrm{HClO}_{4}+0.20 \mathrm{M} \mathrm{RbOH}$ c. $0.50 M \mathrm{HOCl}+0.35 \mathrm{M} \mathrm{KOCl}$ d. $0.70 M \mathrm{KOH}+0.70 \mathrm{M} \mathrm{HONH}_{2}$ e. $0.85 M \mathrm{H}_{2} \mathrm{NNH}_{2}+0.60 \mathrm{M} \mathrm{H}_{2} \mathrm{NNH}_{3} \mathrm{NO}_{3}$
