Replace immutable groups in compounds to avoid ambiguity. In many cases a complete equation will be suggested. Examples: Fe, Au, Co, Br, C, O, N, F. Ionic charges are not yet supported and will be ignored. The platinum or palladium catalyzes the reaction and is not attacked by the sodium peroxide. Sodium peroxide hydrolyzes to give sodium hydroxide and hydrogen peroxide according to the reaction[9]. It is certainly not a double replacement reaction.

The octahydrate is produced by treating sodium hydroxide with hydrogen peroxide. 中文. Sodium peroxide was used to bleach wood pulp for the production of paper and textiles. Find another reaction. Product solution will be a strong alkaline solution due to occurrence of NaOH. It is also used as an oxygen source by reacting it with carbon dioxide to produce oxygen and sodium carbonate: It is thus particularly useful in scuba gear, submarines, etc. 1.1251661393e+053
