Sodium benzoate (NaC7H5O2, “NaA”) is a weak base that is commonly used as a food preservative. The base hydrolysis constant (Kb) for benzoate ion (C7H5O2 - , “A- ”) is 1.6 × 10-10. (a) What is the pH of a 0.25 M NaC7H5O2 aqueous solution? Show work
2. If sodium benzoate, a food preservative, is excreted as such and if calcium propionate, another food preservative, is metabolized to CO2 and H2O, would you consider either of these preservatives to be a nutrient? If so, why? 3. What is the most effective weight loss method? 4. Beer contains maltose. Can beer consumption be detected by analyzing the maltose content of a blood sample? Explain. 5.How many essential amino acids do humans need in their diet 6. What is...
When you ingest the common food preservative, sodium benzoate, it reacts with the hydrochloric acid in your stomach. Show the mechanism and corresponding products for this reaction.
Sodium benzoate (C6H, CO₂Na) is wed as a food Preservative! Part A Calculate the pt in 0.058 M sodium benzateo ka for benzoic acid this (C6Hs CO₂H) is 6. 5x10-5. Part B Calculate the concentrations of all species present (Nat, C oHs CO₂, Colts CO2H H₂oT and OH-) in 0.058 M sodium benzoate.

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)
