Ceria → Ceria ascorbic acid

Participants

Reaction Steps

In these examples, an insoluble adduct of ceria and antioxidant was first formed followed by dissolution in a basic solution. In one example, 1.0 gram (g) of a yellow solid ceria precipitate was added to 50 milliliters (ml) of a 5% (w/w) ascorbic acid aqueous solution. A darker colored precipitate, i.e., an insoluble ceria-ascorbic acid adduct, was formed. The ceria-ascorbic acid adduct was isolated and then readily dissolved in a number of basic solutions as described below.
