This is a basic alphabetical list of the chemicals found in the subnet, all of which are found and used in the real world.

Acidic oxideEdit

Acidioxide The acidic oxide synthesized in Submachine 4 is incorrectly referred to as "acidioxide". Also known as acidic anhydride, it is an oxide that reacts with water to form an acid. The strength of the acid varies depending on the oxidation level and its extent of dissociation. It is unknown exactly which acidic oxide is created in Submachine 4, but due to its corrosive properties, it is presumed that it is strong. In the game, this substance is made by boiling a solution of soap mixed with iron(III) oxide (rust) and naphthalene (mothballs). In truth, this reaction would not produce an acid, or in fact any products, since the starting materials are quite inert.



Examples of brass used in Sub9.

Brass is used extensively in objects found in Submachine 9.

Brass is an alloy made of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying properties.

It is used for decoration for its bright gold-like appearance; for applications where low friction is required such as locks, gears, bearings, doorknobs, ammunition casings and valves; for plumbing and electrical applications; and extensively in brass musical instruments such as horns and bells for its acoustic properties. It is also used in zippers.

Citric acid (C6H8O7)Edit

Citric acid

Citric acid * water.

Citric acid is a weak organic acid present in lemons, limes and generally other citrus fruits. In Submachine 5: The Root it is used to melt a metal box containing a Wisdom Gem.

Citric acid molecule

A citric acid molecule.

The fact that citric acid is not strong enough to dissolve metal in real life leads to many questions concerning why this acid can.

Various theories have been proposed. The leading theory postulates that the Submachine has different chemistry, so the citric acid here could be stronger than in real life. Another possibility is that the tub once contained citric acid, but its contents were changed and hence it now contains a different, stronger acid.

Gold (Au)Edit



Gold is a valuable metal that has been used to make numerous statues. It is a chemical element, atomic number 79, abbreviation Au (lat. aurum). Gold is heavy but very soft, it is the most malleable and ductile metal when pure, also can be molded easily.

Gold structure

A structure made of gold atoms.

Gold is also extremely resistant to acids, so it always stays shiny.

Iron trioxide (Fe2O3)Edit

Iron trioxide
Iron trioxide model

Network structure of iron(III) oxide molecules.

The correct spelling of iron trioxide is actually "iron(III) oxide" or "ferric oxide".

It is mostly used for ceramic applications. When mixed with water, soap and naphthalene in Submachine 4, it hypothetically releases a significant amount of oxygen atoms and iron ions.

Naphthalene (C10H8)Edit

Naphthalene molecule

A naphthalene molecule.

Naphthalene (also known as tar camphor, white tar, albocarbon, or antimite) is commonly used for the production of naphthalene sulfonate polymers which are used to produce concrete and plasterboard. In the game it is mixed with water, soap, and iron(III) oxide to form an unknown acid.

Water (H2O)Edit

Tester with water
Water molecules

Water, in nature, is found as solid, liquid and gaseous (ice, water and steam, respectively). No acid can behave as an acid without water - all acids are aqueous solutions.

Because of its molecular shape and polar nature, all ions can be dissolved in water (aqueous solutions), earning water the nickname "the universal solvent".
