We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

Chemical kinetics — The 'DID YOU KNOW' section states Jacobus van 't Hoff's foundational work on reaction rates and the Arrhenius equation, but the Arrhenius equation was developed by Svante Arrhenius, not van 't Hoff.
Acetic acid — [contradicted] The identity of glacial acetic acid and the acid in vinegar was later established by chemists such as Justus von Liebig, building on earlier work by Carl Wilhelm Scheele who had isolated acetic acid but not definitively identified it as ethanoic
Acetic acid — [contradicted] Interstellar acetic acid was first detected in the Sagittarius B2 North molecular cloud using a combination of radio interferometers and a single-dish radio telescope. :: Interstellar acetic acid was first detected in the Sagittarius B2 North mo
Acid — [contradicted] Many Brønsted–Lowry acids (e.g., hydrogen chloride, acetic acid) can also act as Lewis acids under certain conditions, such as in non-aqueous solvents or when interacting with strong bases, by accepting an electron pair to form a coordinate cova
Aldehyde — [contradicted] claim: Smaller aldehydes such as formaldehyde and acetaldehyde are soluble in water, and the volatile aldehydes have pungent odors. :: The source says 'Smaller aldehydes such as formaldehyde and acetaldehyde are soluble in water, and the volatil
Alkene — [contradicted] Alkenes are also known as olefins and are hydrocarbons containing one or more carbon–carbon double bonds. :: The source states that IUPAC recommends using 'alkene' only for acyclic hydrocarbons with just one double bond, and 'olefin' for the gen
Alkene — [contradicted] Alkenes with four or more carbons exhibit structural isomerism, and many also show cis–trans isomerism. :: The source states that cis–trans isomerism for acyclic mono-enes exists only when the double bond is not the first bond of the chain and w
Base (chemistry) — [contradicted] The concept originally proposed by G.-F. Rouelle in the mid-18th century :: The source says "originally proposed by G.-F. Rouelle in the mid-18th century" is correct; no contradiction found.
Base (chemistry) — [contradicted] Arrhenius bases are metal hydroxides such as NaOH or Ca(OH)2 :: The source says "A base was therefore a metal hydroxide such as NaOH or Ca(OH)2" — no contradiction.
Chemical bond — [contradicted] Bond formation releases energy due to reduction in kinetic energy, not potential energy. :: The source states: 'Energy is released by bond formation. This is not as a result of reduction in potential energy... Instead, the release of energy (and
Chemical bond — [contradicted] Ionic bonds have no particular orientation in space, unlike covalent bonds. :: The source states: 'Often, such bonds have no particular orientation in space, since they result from equal electrostatic attraction of each ion to all ions around th
