Question: What is the molar concentration of acetic acid in a sample of vinegar? Prediction: The manufacture of claims on the label that the vinegar contains 5.0% acetic acid, which translates into a 0.87 mol/L concentration of acetic acid. The concentration of acetic acid in the vinegar sample should be the same. Purpose: If we add acid solution to basic solution to produce water and salt this activity is called titration. It involves carefully adding one …
