Materials and Methods The laboratory procedures were conducted based on the steps provided in ‘An Introduction to Chemical Systems in the Laboratory’1. Specifically‚ 1.90 grams of KCL was weighed in a 250ml beaker and dissolved in 25 ml of deionized water. This solution was then quantitatively transferred to a 250ml volumetric flask. Proper technique is needed for quantitative analysis. This transfer was done to ensure that there was no detectable KCl left in the beaker. After transferring the
