Measure 8.333 mL of 12 M HCl and dilute to 100 mL total volume.
Always add acid to water, never water to acid, dilution is strongly exothermic. Work in a fume hood with PPE.
Every result unfolds the formula and the substituted numbers, with print-ready KaTeX. No black boxes on the bench.
Molar masses, pKa, NN thermodynamics, Antoine and NMR data are cited to IUPAC, NIST, and the primary literature, never guessed.
Add acid to water, exothermic warnings, GHS pictograms, and an advisory safety layer surface right where the protocol does.
Everything runs on your device. No account, no upload, no tracking. It works on the plane and in the cold room.
