About

Solution Equilibria Lab

Features
Read full description

The Solution Equilibria Lab application is designed to calculate equilibrium constants (dissociation constants of weak acids and solubility products of sparingly soluble salts) from acid-base and precipitation potentiometric titration data in aqueous solutions. It covers titrations of weak monobasic acids and their mixtures, dibasic acids, and the precipitation of sparingly soluble salts of 1:1 and 1:2 valence types. The application accurately processes experimental data and determines the thermodynamic constants of the corresponding equilibrium processes. This powerful analytical tool is designed for chemists, researchers, teachers, and students to quickly and reliably estimate equilibrium constants from potentiometric titration data. Whether in the lab or the classroom, this application provides accurate calculations in real time, excellent solution visualization via diagrams, a user-friendly interface, and the ability to export the solution to a file for further work. The Solution Equilibria Lab app is designed for both scientists and students and is now optimized for mobile devices.
