Potassium nitrate is the oxidizer used in black powder. Although other oxidizers are stronger(potassium perchlorate for example), it must not be replaced by them. If the term used is black powder, potassium nitrate is the only oxidizer that ought to be used.
Black powder is a traditional gunpowder made from a mixture of sulfur, charcoal, and potassium nitrate. Flash powder is a more modern pyrotechnic composition that produces a bright flash of light and a loud noise when ignited, typically composed of a fine fuel powder and a strong oxidizer. Flash powder is more powerful and volatile than black powder.
More of a formulation than a formula, Strontium Nitrate is a weak oxidizer and responsible for the red color of flame, Potassium Nitrate is a strong oxidizer and also burns with a red flame, and potassium perchlorate is a strong oxidizer and burns with red flame. The fuels used in a road flare are sulfur, charcoal,sawdust, aluminum powder and magnesium powder. The proportions of the various fuels and oxidizers vary with different manufacturers. Also note that aluminum powder and magnesium powders are used to brighten the flames and sawdust subdues the flame and prolongs the burn. The compositions are similar to black powder (gunpowder).
The black powder formed on copper powder in an experiment is likely copper oxide. When copper is exposed to air, it can react with oxygen to form copper oxide, which appears as a black powder. This is a common reaction observed with metals that are prone to oxidation.
An oxidiser, or an oxidising agent. Spelled with a 'z' if you're American.
Clorox bleach is an oxidizer because it tends to cause other substances to lose electrons and undergo oxidation reactions.

Gunpowder- both the original black powder, and today's smokeless powder, is a combination of a fuel and an oxidizer to make that fuel burn. It must have both to work. One without the other is useless.
To the best of my knowledge unless you are a convicted felon you can own a black powder gun.
you can't buy flash powder. it is used to make firecrackers and explosives, so it is not commercially available. You can make it from an oxidiser and a metallic fuel such as KClO4 and Aluminium.
Larger grain black powder, such a fG or ffG. Black powder substitutes, such as Pyrodex are not intended for use in propelling fireworks. Pyrodex R could be tried- rmember it is measured not by weight, but by volume.
The two common forms are black powder, and smokeless powder. Both are low explosives, used to propel a bullet. While they arer different chemically, both contain a fuel and an oxidizer mixed together. When ignited, they burn very quickly, producing rapidly expanding gasses (which is what propels the bullet)
No, it's a reducing agent
The grey powder coating on a sparkler is typically made of a mixture of fuel and an oxidizer. The fuel provides the material that burns and produces the spark, while the oxidizer supplies the oxygen needed for combustion. Additionally, the grey coating may also contain metal powders or salts to create colorful sparks when ignited.
You cannot buy flash powder online or at any other store - that would be like buying C4 over the Internet. You would need to make it yourself from an oxidizer and aluminum or magnesium powder.
Black powder guns are not federally controlled and can be shipped by mail to you. There are a few places (mostly major cities that do restrict black powder, it is always best to check with local law enforcement first. You don't need a yard full of black suburbans and guys in jumpsuits.
Black powder absorbs moisture from the atmosphere
Manganese dioxide (MnO2) is a black powder.
