Abstract
Sodium hypochlorite has been used as a bleaching agent and disinfectant for over 200 years, and manufacturers produce more than 2 billion gallons of aqueous NaOCl every year. Yet despite that long history, chemists have only just determined its crystal structure ( Angew. Chem., Int. Ed. 2021, DOI: 10.1002/anie.202108843 ). “I think it’s one of those things that was hiding in plain sight, that somehow slipped through the cracks,” says McGill University’s Tomislav Friščić, who led the work. Solid sodium hypochlorite is highly hydrated (NaOCl∙5H 2 O) and rapidly liquefies at room temperature, so Friščić’s team carried out X-ray diffraction on a single crystal of the solid at –100 °C. This revealed alternating layers of hydrated sodium (Na + ) and hypochlorite (ClO – ) ions in the crystal. Each Na + is surrounded by an octahedron of six water molecules, while the other layer contains a chain of water

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
