Abstract/Summary

Laboratory experiments are indispensable tools for students because it helps them understand their lessons effectively. However, some schools are deprived from doing these experiments due to the unavailability of glassware and reagents. This study aimed to modify experiments in Analytical Chemistry using alternative laboratory glassware and readily available reagents. The results were compared to the standard methods use in the analytical laboratory. These experiments involved only classical methods of analysis. Standard methods made use of the standard laboratory glassware and reagents while the modified method involved the use of alternative such as a syringe for a burette, catsup bottles for volumetric flasks, mayonnaise bottles for Erlenmeyer flasks or reagents like muriatic acid for hydrochloric acid (HCI), liquid sosa for sodium hydroxide (NaOH) and betadine for iodine solution (I2) All pieces of glassware were calibrated prior to the performance of the experiments. Results of the modified experiments do not differ significantly compared to the results obtained using the standard method. Statistical analysis, specifically F-test, further established that the variances of the two methods are the same. T-test showed that there was no significant difference between the average results of the standard and that of the modified experiments. In view of this, the modified method is a feasible substitute for the standard method and could be used for the analysis of real samples.
