Determine the pH if a solution that consists of 175.0mL of 0.085M Benzoic acid and 100.0mL of 0.045M Sodium benzoate 

Ka of benzoic acid if 6.3x10-5


Expert Answer

Step 1

Given information:

Ka of benzoic acid = 6.3 × 10-5.

Benzoic acid = 175 mL of 0.085 M

Sodium benzoate = 100 mL 0.045 M


Total volume of solution= 175 + 100= 275 mL
