Sodium percarbonate is a chemical, an adduct of sodium carbonate and hydrogen peroxide (a perhydrate), with formula 2Na2CO3 · 3H2O2. It is a colorless, crystalline, hygroscopic and water-soluble solid.[1] It is used in some eco-friendly cleaning products and as a laboratory source of anhydrous hydrogen peroxide.
This product contains the carbonate anion, and should not be confused with sodium peroxocarbonate Na2CO4 or peroxodicarbonate Na2C2O6, which contain different anions.

Uses

As an oxidizing agent, sodium percarbonate is an ingredient in a number of home and laundry cleaning products, including bleach products such as OxiClean, Tide laundry detergent,[1] and Vanish.[5] It contains no phosphorus or nitrogen. Dissolved in water, it yields a mixture of hydrogen peroxide (which eventually decomposes to water and oxygen) and sodium carbonate ("soda ash").[1]
2Na2CO3.3H2O2 → 2Na2CO3 + 3H2O2 [5]
Sodium percarbonate can be used in organic synthesis as a convenient source of anhydrous H2O2, in particular in solvents that cannot dissolve the carbonate but can leach the H2O2 out of it.[6]
