volume data from simulated and real potentiometric titration curves by two methods: i) graphical representation of curves, assisted by cubic splines interpolation and smoothing of derivative curves, for accurate evaluation of inflections (end-points) ii) determination of concentrations and refinement of pKa values by multiple nonlinear regression (based on the Solver supplement of Excel), essential for difficult titrations with undefined inflections, e.g., acid rain. Valuable for teaching, generation of unlimited titration exercises and evaluation of the feasibility and accuracy of new titrations.
* Simulation and overlay of acid-base titration curves of any complexity, with or without random errors in pH and/or volume. * pH calculation of any aqueous solution of strong and weak acids, bases, salts, buffers and mixtures of up to 7 polyprotic systems (>40 species), with buffer capacity and activity coefficient estimation Features of this powerful suite of MS Excel spreadsheets embrace: It also offers enhanced functionality through HTML 5, offline modes, background processing, notifications, and more.A pH Calculator, a Virtual Titrator, a Real Titration Data Analyzer, a Distribution Diagram Generator - thats CurTiPot, the all-in-one freeware to learn, teach and work with chemical equilibrium of acids, bases, salts and buffers at home, classroom, interactive "dry lab", routine or research laboratory. This process simplifies the way you access personal content and the web. In the future, there may be other tab types that do not host the standard browser toolbar.Ĭhromium is a speedy and efficient browser that uses search as its primary form of navigation. The tab is the equivalent of a desktop application's title bar the frame containing the tabs is a convenient mechanism for managing groups of those applications. The project has avoided putting unnecessary things into the User Interface to make a more intuitive, user-friendly experience. It was designed to provide a safer, faster, and more stable way to experience the web for all users.Ĭhromium is a tabbed window manager or shell for the internet rather than a browser application.
