Teotizo Haven

Teotizo Haven brings the chemistry laboratory to your mobile device. Perform acid-base titrations with a fully animated virtual bench — drag the stopcock knob on the burette, watch the flask change colour as your chosen indicator responds to each pH shift, and track every data point on a live pH-versus-volume curve with automatic equivalence-point detection. Choose from ten built-in titration protocols spanning every major acid-base type: strong acid versus strong base pairs, weak acids such as acetic, formic, oxalic, carbonic, and citric acid against strong bases, weak bases such as ammonia and methylamine against strong acids, and polyprotic systems including phosphoric and citric acid. Pair each run with one of twelve authentic pH indicators — phenolphthalein, bromothymol blue, methyl orange, and more — and watch the flask colour shift at the true transition pH. Go deeper with the built-in reagent and solution editor to customise concentrations and pKa values, or build entirely new solutions. Every completed run is saved to your local archive, where you can revisit the full curve, read back the half-equivalence pKa, and attach a photo from your physical bench. The post-run analysis screen adds a speciation chart showing how each species distributes across the pH range. Toggle the first-derivative overlay to pinpoint the equivalence inflection, and explore nine expandable method notes covering buffer plateaus, indicator selection, polyprotic behaviour, dilution effects, and more. Teotizo Haven is designed for chemistry students and educators who want to build genuine intuition about pH curves, equivalence points, and indicator behaviour — whether preparing for a practical exam, teaching a class, or exploring analytical chemistry at your own pace. All computation runs on-device with no account, no login, and no network connection required.
