How to Use These Programs Ah what a wonderful tool the computer is in the research chemistry lab! We use it to collect data from instruments, analyze the data, and generate and print reports. Using the time saved we can devote more time to analyzing the results of the experiments and comparing them to our theoretical models. More often than not, we also use the computer to generate the data from these theoretical models that we compare to the data collected. The programs in this issue allow beginning students in chemistry to see how the research chemists use computers in this manner. The KineticsLab program makes use of the IBM Personal Science Laboratory interface to collect data from a kinetics experiment. KineticsLab uses the computer to collect data allowing much more data to be collected in a single run of the experiment than can be collected by hand. This large data set can be analyzed using the computer more easily than much smaller data sets can be analyzed by hand and calculator. Also no data entry errors are introduced since the data were collected by the computer. Calculations on the data are readily performed and the results graphically displayed and printed if desired. The time saved enables more trials to be done or experiments to be repeated at various conditions. TITRATE does not collect titration data but can readily be used to compare such data with theoretical results. Experimental data can be imported into TITRATE and compared with theoretical titration curves generated by the program by plotting both curves on the same axes. TITRATE also provides a feel for doing titrations by including a simulation. This simulation in combination with the ability to assign unknowns makes TITRATE an effective pre-laboratory or post-laboratory exercise. Hardware and Software Requirements Programs in Series B of JCE: Software are designed for IBM PS/2, PC, or PC-compatible microcomputers with 640K of RAM and one floppy disk drive. VGA or compatible graphics and PC- or MS-DOS 3.1 or later are also required. Disk drives with a capacity of 800 K or larger are recommended. KineticsLab also requires an IBM Personal Science Laboratory with temperature probe and photometric or radiometric probe. Additional materials are also required to build the foamtronic photometer. |
