Oxidation Rate Constants of Antioxidants Sodium Sulfite, Sodium Bisulfite and Sodium Pyrosulfite

Time : 2021-04-21 Hits :

Sodium sulfite, sodium bisulfite and sodium metabisulfite are three commonly used Antioxidants.

We use kinetic methods to determine their solubility in water The rate constant of the reaction

with oxygen in the liquid.

The results show that sodium sulfite, sodium bisulfite and sodium metabisulfite are in aqueous solution with

Oxygen reactions are all zero-order reactions. Due to the dissociation equilibrium of these three antioxidants in solution,

When the pH of the solution is the same, the three antioxidants are essentially the same.
