What is Sodium Percarbonate?
Sodium Percarbonate is a chemical compound used as an alternative for hydrogen peroxide with the formula C2H6Na4O12. Sodium Percarbonate is prepared by adding sodium peroxide slowly to ice-cold absolute alcohol. Sodium percarbonate dissolves relatively fast in the water, releasing sodium carbonate and hydrogen peroxide in the solution. The slight amount of moisture which is present already in the atmosphere is sufficient to bring about the decomposition of the percarbonate.
Other names – Peroxy sodium carbonate, Oxyper

Chemical Properties of Sodium Percarbonate – C2H6Na4O12
- Sodium percarbonate reacts with sodium bisulfate form sodium persulfate, sodium carbonate and water. The chemical equation is given below.
C2H6Na4O12 + 6NaHSO4 → 3Na2S2O8 + 2Na2CO3 + 6H2O
Uses of Sodium Percarbonate – C2H6Na4O12
- Sodium percarbonate is antiseptic and deodorant. In an aqueous solution, it may be used as an antiseptic for wounds in place of hydrogen peroxide.
- It has a beneficial effect on bicarbonate hydrogen peroxide mixtures in the area of oral hygiene and therapy.
- Used as an alternative for alkaline treatments. The minerals which can be bleached using H2O2 include chalk, rutile, holmites and natural silicates.
