Final answer:
The ratio of the concentration of sodium acetate to acetic acid at pH 5.75 is 10:1.
Step-by-step explanation:
The ratio of the concentration of sodium acetate to the concentration of acetic acid at pH 5.75 can be determined using the Henderson-Hasselbalch equation:
Sodium acetate/acetic acid = 10^(pH - pKa)
Substituting the given values:
Sodium acetate/acetic acid = 10^(5.75 - 4.75)
Sodium acetate/acetic acid = 10^1
Sodium acetate/acetic acid = 10
Therefore, the ratio of the concentration of sodium acetate to the concentration of acetic acid is 10:1.
