Sodium benzoate (NaC7H5O2) is sometimes used as a preservative in foods. Benzoic acid is the conjugate acid of the benzoate ion, which has a Ka value of 6.3 x 10-5. Calculate the Kb value for the benzoate ion. (1 mark) Use the Kb value for the benzoate ion from part a, calculate the pH of a 0.215 M solution of the sodium benzoate. (Ignore x method, 4 marks)
Benzoic acid is a weak acid that has antimicrobial properties. Its sodium salt, sodium benzoate, is a preservative found in foods, medications, and personal hygiene products. Benzoic acid dissociates in water: C6H5COOH⇌C6H5COO−+H+ The pKa of this reaction is 4.2. In a 0.76 M solution of benzoic acid, what percentage of the molecules are ionized? Express the percentage numerically using two significant figures.
