Phasequilib vs Potentiometric Titration

Основана на лабораторной работе №3 из методического пособия "Массообменные процессы. Руководство к практическим занятиям в лаборатории процессов и аппаратов нефтегазопереработки" (Т.В. Прокофьева, В.А. Щелкунов, Е.Б. Федорова). Приложение имитирует работу лабораторного прибора, предназначенного для определения коэффициента относительной летучести и составов равновесных паровой и жидкой фаз смеси изооктана и толуола. Приложение имеет встроенную инструкцию и функцию проверки ответа.

See the chemistry behind every titration curve. Potentiometric Titration brings interactive chemistry models, guided practice and clear results to your iPhone and iPad. Explore how concentration, volume and temperature affect a titration, locate equivalence points, and turn your calculations into reports you can share. Designed for students, educators and anyone studying analytical chemistry, the app connects numerical results with the chemical principles behind them. EXPLORE ACID-BASE TITRATIONS Model strong and weak acids, acid mixtures, dibasic acids, and combined monobasic and dibasic systems. Adjust the input conditions and titrant steps to explore how the curve changes. GO BEYOND ACID-BASE Investigate precipitation titration with 1:1, 1:2 and 1:3 salt models. Read the method explanation alongside your inputs and examine the calculated results. SEE CURVES AND EQUIVALENCE POINTS Plot potential against titrant volume with E(V), examine the differential curve with dE/dV, or display both together. Zoom, pan and inspect chart points. View detected equivalence points, the data-point count and the volume range, then explore the calculated values in a table. LEARN THROUGH GUIDED PRACTICE Work through 20 practical tasks on strong-acid titration. Load a task's parameters into the calculator, explore the results, and test your understanding with five-question quizzes. Review answer explanations, retry at your own pace, and keep track of your progress and best scores. RETURN TO YOUR CALCULATIONS Browse your saved history, filter by titration type, and search by method, date or notes. Reopen a calculation to continue exploring. Export history as JSON and import it on another device to transfer your work. CREATE REPORTS AND EXPORT DATA Build PDF reports with your title, author, sample details and notes. Choose which charts, calculated data and input parameters to include, and review the chart preview before exporting. Export calculated tables as CSV or Excel, and export your history as JSON, PDF, Excel or CSV. MAKE IT YOURS Choose a light or dark theme, customize chart colors, and switch the app language in Settings. The interface supports English, German, Spanish, French, Hindi, Russian, Thai, Ukrainian and Chinese. Built-in help explains the theory, methods and app workflows. From your first reference curve to a complete report, make every calculation an opportunity to understand more.
