 Hydrogen peroxide - Wikipedia, the free encyclopedia
Hydrogen peroxide was first isolated in 1818 by Louis Jacques Thénard by reacting barium peroxide with nitric acid.
Peroxide was used very successfully as an oxidizer for early World-War-II era German rockets, and for the low-cost British launchers, Black Knight and Black Arrow.
Hydrogen peroxide is manufactured today almost exclusively by the autoxidation of 2-ethyl-9,10-dihydroxyanthracene to 2-ethylanthraquinone and hydrogen peroxide using oxygen from the air.

A leak of high-test peroxide (85%-98% hydrogen peroxide) from a torpedo caused an explosion that sealed the fate of the Russian submarine Kursk.
Hydrogen peroxide as oxidizer was experimented with in the 1940's and 50's for submarines to use while submerged: it was found to be to noisy and maintenance demanding compared to the conventional diesel-electric power system.
High strength peroxide (also called high-test peroxide, or HTP) must be stored in a vented container to prevent the buildup of pressure from natural spontaneous decomposition leading to the eventual rupture of the container.

Sodium, Na, is a Alkali Metal element, found in Group Ia of the periodic table.
Sodium metal is highly reactive and tarnished readily in air due to the formation of a layer of Sodium Oxide on the surface of the metal.
Sodium is detected in its compounds by the bright yellow colouration which it imparts to flames when burned and by spectroscopic methods.

Sodium peroxide (Class 5) in drums; solid that reacts violently with water and organic materials; powerful oxidizer that decomposes by heat to free oxygen and may cause fire and explosion in contact with combustibles
Summary: During loading of the German ship Burgenstein, a drum with sodium peroxide was damaged by a fork-lift truck and part of the content was spilled on plastic materials on deck.
This was a serious mistake considering the cargo of 1) sodium peroxide that reacts vigorously with water, and 2) cyanides that emit hydrogen cyanide when wet.

Sodium Peroxide is said to "ignite and/or explode in contact with organic matter or readily oxidizable substances" (Merck Index 12th ed.).
The "classic" Sodium Peroxide demo is to pour some sodium peroxide on top of a few sheets of paper and drop water on it.
Just a few seconds after the water soaks through the paper into the sodium peroxide the beaker spontaneously erupts into a violent, roaring/crackling flame that reaches over a few feet in height and is hot enough to quickly melt through the bottom of the beaker.

Sodium peroxide is used in laundry bleaches, as it reacts with water to make hydrogen peroxide, a bleaching agent.
Besides hydrogen peroxide, the reaction makes sodium hydroxide (lye), which keeps the solution alkaline.
Hot water and an alkaline solution are both needed in order for hydrogen peroxide to work best as a bleach.

Fortunately, you can make sodium carbonate that will be very pure, and do it pretty easily.
This is probably the purest form of sodium carbonate that's reasonably priced; even so, it may require some stirring or starting with warm/hot water to get it to dissolve completely; carbonates are just not very soluble unless the water is slightly acidic.
While sodium peroxide is a strong base and oxidizer, it is not as hazardous as metallic sodium.
