Discussion/Conclusion:


The purpose of this lab was to determine how "fast" a chemical reactions occurs by determining the rate constant. Our group was successful in doing this. The process involved putting NaOH, crystal violet solution, and deionized water all into a cuvette in specific amounts. The data collection system allowed us to calculate the reaction rate constant for each trial. For trial 1 it was 0.0064, for trial 2 it was .0076, and for trial 3 it was 0.0164. We found the average rate constant to be 0.0101. Two sources for error that may have occurred are not adding and mixing the crystal violet solution quickly enough or not wiping the cuvette with a Kimwipe thoroughly. Both of these errors would yield inaccurate recording and moreover, results. To improve this experiment in the future, it would be important to emphasize fast mixing of the substances and thorough cleaning of the cuvette before placing it in the colorimeter.
