Best answer
Correct Answer - Option 4 : C6H5COONa

The Correct Answer is C6H5COONa.

  • Sodium benzoate has the chemical formula C6H5COONa and it is a preservative.
  • With an E number of E211, it is a commonly used food pickling agent.
  • It is the benzoic acid sodium salt which occurs in this form when dissolved in water.
  • It can be produced by benzoic acid reacting to sodium hydroxide.

  • Sodium benzoate is produced by benzoic acid neutralisation and is itself commercially produced by partial oxidation of toluene with oxygen.
  • As a result of its ability to bind amino acids, sodium benzoate is used as a therapy for urea cycle disorders.
  • This results in the excretion of these amino acids and in a reduction in the amount of ammonia.
