Instead, institutions have opted to use it as a supplement, Mr. No college or university has used the virtual lab to replace a campus-based lab entirely. Woodfield says the inorganic-chemistry version of the software can simulate 10,000,000,000,000,000 - or 10 16 - different outcomes, depending on what chemicals are mixed and how the student conducts the experiment.Ībout 20 institutions around the country have purchased licenses to use the program. Virtual ChemLab, which allows students to complete lab assignments on a computer and submit their lab reports online, is available for labs in organic synthesis, inorganic qualitative analysis, and quantum mechanics. Woodfield, an assistant professor of chemistry. The software, called Virtual ChemLab, was developed by Brian F. ![]() The students work with computer software that simulates what would happen if, for instance, two dangerous chemicals were mixed together, or the power of a laser beam were amplified. These errors can be ignored, which will produce results and errors typically found in high school or freshman-level laboratory work, or the buoyancy and volumetric errors can be measured and included in the calculations to produce results better than 0.1% in accuracy and reproducibility.A Brigham Young University faculty member has found a way for students to get hands-on chemistry experience without actually putting their hands on any chemicals. Systematic and random errors in the mass and volume measurements have been included in the simulation by introducing buoyancy errors in the mass weighings, volumetric errors in the glassware, and characteristic systematic and random errors in the pH/voltmeter and conductivity meter output. A smaller set of potentiometric titrations can also be performed. The pH of these titrations can be monitored using a pH meter, an indicator, and a conductivity meter as a function of volume, and this data can be saved to an electronic lab book for later analysis. Acid-base titrations can be performed on any combination of mono-, di-, and tri-protic acids and mono-, di-, and tri-basic bases. ![]() The available laboratory equipment consists of a 50 mL buret, 5, 10, and 25 mL pipets, graduated cylinders, beakers, a stir plate, a set of 8 acid-base indicators, a pH meter/voltmeter, a conductivity meter, and an analytical balance for weighing out solids. ![]() The virtual titration laboratory allows students to perform precise, quantitative titrations involving acid-base and electrochemical reactions. As in all of the virtual laboratories, the main focus of the titration laboratory is to allow students the ability to explore and discover, in a safe and level-appropriate setting, the concepts and ideas that are important in the study of acid-base and electrochemistry and the procedures and techniques that form the foundation of titrimetric methods. In this virtual laboratory, students are free to choose equipment, select reagents, perform titrations, and make the choices and decisions that they would confront in an actual quantitative experiment and, in turn, experience the resulting consequences. Welcome to Virtual ChemLab: Titrations, a realistic and sophisticated simulation of quantitative acid-base and potentiometric titration experiments.
