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.

Curium — The claim that one tonne of spent nuclear fuel contains approximately 20 grams of curium is inaccurate; typical spent nuclear fuel contains only a few grams per tonne, not 20 grams.
Curium — [contradicted] One tonne of spent nuclear fuel typically contains only a few grams of curium, not 20 grams. :: Most curium is produced by bombarding uranium or plutonium with neutrons in nuclear reactors – one tonne of spent nuclear fuel contains ~20 grams of
Dalton (unit) — The entry incorrectly states that from 2026 the dalton will no longer be accepted for use with the SI by the BIPM; the BIPM has not announced such a change and the unit remains accepted as of the latest SI Brochure.
Dalton (unit) — [contradicted] The 2019 revision of the SI redefined the kilogram by fixing the Planck constant, enhancing traceability and accuracy in atomic mass measurements while the dalton's definition via carbon-12 remains unchanged. :: The source states: 'The definitio
Haber process — The first pilot plant began operation in 1910, not 1911.
Haber process — The Oppau plant reached about 20 tonnes per day in 1913, not 1914.
Hafnium — The statement about the longest-lived nuclear isomer 178m2Hf being at the center of a controversy for its potential use as a weapon is misleading; the controversy was about triggered energy release, not specifically as a weapon.
Haloalkane — Chloroethane was not produced in the 16th century; the first synthesis is generally attributed to the 18th century, with earlier work in the 17th century, not the 16th.
Distillation — [contradicted] According to British chemist T. Fairley, neither the Greeks nor the Romans had a term for the modern concept of distillation :: The source states 'neither the Greeks nor the Romans had any term for the modern concept of distillation' (same claim
Electrolysis — [contradicted] Electrolysis is a technique that uses direct electric current (DC) to drive an otherwise non-spontaneous biological and physical reaction. :: The source says "to drive an otherwise non-spontaneous biological and physical reaction" – source text:
Electrolysis — [contradicted] Electrolysis is a foundational technique in chemistry and manufacturing, enabling the separation of elements from naturally occurring sources such as ores. The Hall–Héroult process for aluminum electrolysis revolutionized industry by drastically
Environmental chemistry — [contradicted] Environmental chemistry is distinct from green chemistry, which seeks to reduce potential pollution at its source. :: The source article says 'It should not be confused with green chemistry, which seeks to reduce potential pollution at its sourc
