At the presence of oxidizing agent it exhibits reduction properties in acidic, basic and neutral solutions:
Cl2  +  H2O2  --------------------->   2HCl  + O2 
Ag2O  + H2O2 ----------------->   2Ag + H2O + O2
2KMnO4  +  5H2O2 +3H2SO4 ---------------->  2MnSO4 + 5O2 + K2SO4 + 8H2O.

Sodium perborate, Na2H4B2O8, is made by reacting borax with sodium hydroxide to give sodium metaborate (NaBO2) which is then reacted with hydrogen peroxide to give hydrated sodium perborate.Na2B4O7 + 2 NaOH → 4 NaBO2 + H2O2 NaBO2 + 2 H2O2 + 6 H2O → [NaBO2(OH)2 x 3 H2O]2Sodium perborate is useful because it is a stable, source of peroxide anions. When dissolved in water it forms some hydrogen peroxide, but also perborate anion (B(OOH)(OH)3-), which is activated for nucleophilic oxidation
