Question 1

Vinegar is a 5.0% solution by weight of acetic acid (CH3CO2H) in water. Given that Ka = 1.8 × 10-5 for acetic acid and assuming the density of vinegar to be 1.00 g/cm3, what is the pH of this vinegar solution?
◦ 2.87
◦ 2.00
◦ 4.74
◦ 2.41

Question 2

Vinegar is a 5.0% solution by weight of acetic acid (CH3CO2H) in water. Given that the pH for acetic acid is 2.41, the Ka = 1.8 × 10-5 and assuming the density of vinegar to be 1.00 g/cm3, what is the percent dissociation of acetic acid in vinegar?
◦ 0.47%
◦ 1.5%
◦ 5.0%
