Weak Points: No description of the theory/calculations behind experiment




I’m sure many of you reading this can remember your first acid-base titrations in chemistry class—the thrill of watching the pH indicator change color, and the fear of opening the stopper too much and flooding your sample with acid (or base). While the physical experience of doing titrations in the lab is really worth experiencing, a viable alternative for educators who don’t have access to the necessary equipment or resources is the Titration Simulator app. This app displays a virtual burette and flask and allows students to “open” the burette to release liquid into the beaker. An image of the flask (showing the pH indicator) is displayed on the left of the screen, as is a close-up view of the volume gradations of the burette. Users can choose whether acid or base is placed in the burette, and can select from four different acids and four different bases.
