Welcome to The Virtual Laboratory


This page is an index file on Virtual Laboratory Activities collaboratively created with the IrYdium project at Carnegie Mellon University. There are a variety of activities which can be accessed from this page. These include virtual lab assignments embedded in html pages, interactive quizzes and copies of handouts on assignments designed to be run off the class CD, or in the UALR chemistry computing lab (SCLB-263). This page will also provide links to new material as we develop it (ASP embedded assignments).

If you have any questions or comments please feel free to contact me at rebelford@ualr.edu.


Note: Many of these pages have the Virtual Lab embedded in an adjustable frame and you should adjust the size of the frame to best fit your monitor.
Virtual Exercise
Description
Exp. 1 Scientific Method   This is a good "first exercise" and involves a forensic style investigation of a virtual simulation of a "toxic mercuric spill". That is; "Which barrel contains the mercury?
Exp. 2 Dilution Problems    Stockroom simulation with concentrated acids and bases. Questions embed a bit of descriptive chemistry on top of dilution problems
Exp. 3 Aqueous Salt Solutions  A virtual lab with tutorial on creating aqueous salt solutions
Exp. 4.1
Exp. 4.2
Exp. 4.3
Enthalpies of Neutralization  Using the 3 labs, determine the enthalpy of neutralization for acetic acid and ammonia without ever mixing them.   Hint, apply Hess's Law to the problem.
Exp. 7 Gravimetric Analysis of Unkown Lead Solutions   This is a practice exercise embedded in an interactive quiz. It is modeled after a real virtual post lab assignment which was coupled to a gravimetric analysis experiment and can be obtained at Print Experiment 7.  Many of the students simply transfered procedures from the real lab to the virtual lab and failed to precipitate all the lead out. That is, the virtual solution was more concentrated than the real one and they failed to account for all the lead.
Exp. 8 LeChatlier's Principle   This is a simulation of a lecture demonstration on LeChatlier's principle. It shows the effect of chloride, silver and temperature on the equilibrium of the blue [CoCl4]-2 and pink [Co(H2O)6]+2 ionic complexes
Exp. 9 Creating a pH Scale   Create a pH scale using the method of successive dilutions.
Exp. 8 Prelab Acid Base Titrations  A prelab experiment designed to help you run the real lab
