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.
