Analysis
Eight chapters — fundamentals, atomic structure, the periodic table, chemical bonding, physical states, solutions, electrochemistry, chemical reactivity — identical in title and order to KP's Chemistry 9, and convergent down to shared section headings such as §4.1 "Why do atoms form chemical Bonds?". This is architectural convergence on National Curriculum 2006, not copied prose. A1 2 covers a history-of-science strand and nothing devotional: the SLO "Explain the contribution of Muslim scientists in the development of chemistry" at PAGE 5 and a Jabir ibn Hayyan credit table at PAGE 6–7, with no scripture anywhere in the book. A7 is a 5 purely by absence — zero female-marked tokens in 42,021 words, one of only five English-medium files in the entire corpus with none at all. Two further absences a researcher should note: climate change is mentioned zero times, and there are no careers sections and no web links. A newer 2026 Urdu edition of this cell exists; the English copy held here is the 2022–23 one.
Evidence tier
scanned English OCR — quotation permitted after re-verification by exact string match.
Measured scores
Axes not listed were not scored for this book — coverage is uneven by design. All axes run 1–5, where 1 is the secular/pluralist/open pole. See the method.
Evidence recorded 1
Three kinds, deliberately styled apart. A quotation is verbatim wording and is only ever taken from English-medium text. An observation describes structure or theme — the only kind permitted for Urdu and Sindhi material, which this project never quotes. An absence is a negative result: a probe was run and returned nothing, which is the weakest claim made anywhere on this site.

The checksum is of the exact file these findings were computed from, so anyone can prove they hold the same bytes. The retrieval date is when this copy was fetched to the project's own disk, not a formal web-archive capture. Boards and mirrors reprint and reorganise continuously, so a source link may not resolve, and may not serve the same edition if it does. The bibliographic record above — board, class, subject, medium, curriculum, edition, approval reference and page count — is what identifies the book; the link is a convenience. This project does not republish the PDF itself, for the copyright reasons set out in about.
Identifiers and permanent link
| Record ID | stbb-chemistry-9-en |
|---|---|
| Permanent link | /books/stbb-chemistry-9-en/ |
| This record as data | /books/stbb-chemistry-9-en.json · whole dataset |
The record ID is an accession number that happens to be readable. It never changes, even if the metadata encoded in it turns out to be wrong — if this book's board, class, subject or medium is corrected, the correction appears in the fields above and the ID stays as it is. That is the only way a link made today still resolves in ten years. The full rule is in the standards.

If the edition is misidentified, a score does not survive its evidence, the source link is wrong, or a passage is unfairly characterised, that is worth reporting and will be acted on whether or not the correction suits the argument. Corrections are published in the corrections log, never quietly patched. This applies fully to the board that publishes this book: any reply will appear beside the finding it concerns, under the right of reply.
