Potentiometric Titration vs Pocket Experiments Science Lab

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.

Twenty-six rooms. Not a workbook — a bench in each one. You set the parts out yourself, turn the knobs, and measure with the instruments. • Hang as many weights as you like anywhere along a balance beam, and even it up • Drag molecules onto the bench and see what they form • Set a magma's silica and the depth where it freezes, erupt it, then look at the rock through a hand lens and measure the grains • Stretch two strings, detune one, and listen to the beats • Drop three seismometers on a map; three circles meet at one point, and that point is the epicenter Every number is measured off the picture. Nothing here works a value out of a formula and then "checks" it against the same formula. The grains under the lens are really drawn, and their size is really measured. Turn a knob and the picture changes; when the picture changes, the numbers change with it. Every room has three steps: 1. Move it — turn one knob and watch what changes 2. Count it — line the measurement up against the formula and look at the gap 3. Check it — one question, and the reason either way Every room also has a question box. Clear it and the room moves up a tier: none → bronze → silver → gold. There are 78 questions in all. But the questions are not the main act. Playing with the bench is; a question is the detour you take when you think “wait — could I actually build that?” The topics are middle school and high school science: forces and motion, springs and buoyancy, pendulums, circuits, electromagnets, ray optics, lenses, sound, changes of state, solubility, titration, electrolysis, chemical reactions, preparing and collecting gases, the microscope, cell division, photosynthesis, flower structure, heredity, strata, rocks and volcanoes, earthquakes, and the sky. Three neighbors of science come along too: probability, logic gates and regular expressions. ADS AND THE ONE-TIME PURCHASE The app is free and shows ads: a banner along the bottom of the screen, and a full-screen ad when you open the app. All 26 rooms and all 78 questions are open from the first launch. There is exactly one in-app purchase and all it does is turn the ads off — it unlocks nothing and adds nothing. It is a single one-time purchase with no subscription (¥5,000 in Japan; the price for your country is shown in the app). Not based on, or affiliated with, any particular textbook.
