Question

Determine the mass percent of acetic acid in vinegar by

A) Distillation
B) Titration
C) Filtration
D) Evaporation

Answer 1

To determine the mass percent of acetic acid in vinegar, you can use either distillation or titration methods. Filtration and evaporation are not suitable methods.

Step-by-step explanation:

To determine the mass percent of acetic acid in vinegar, there are multiple methods you can use. Here are the steps for each method:

A) Distillation:

1. Calculate the number of moles of acetic acid in the sample
2. Calculate the number of liters of solution from its mass and density
3. Use these results to determine the molarity of the solution

B) Titration:

1. Determine the mass of the water in the sample and calculate the number of moles of water
2. Determine the mole fraction of acetic acid by dividing the number of moles of acetic acid by the total number of moles of substances in the sample

C) Filtration:

Filtration is not a suitable method for determining the mass percent of acetic acid in vinegar.

D) Evaporation:

Evaporation is not a suitable method for determining the mass percent of acetic acid in vinegar.
