Unformatted text preview: 3. Wet Samples The results of the experiment would be different if the copper ammine complex was not completely dry because the weight of the complex would be different. It would also include the weight of the methanol that did not dry away from the complex. Sample Calculation: M 1 V 1 = M 2 V 2 If the volume of the NaOH was not correct because the sample did not dry enough, then the volume of the HCl would also be incorrect. The substance must dry completely before analysis. 4. Exercise The absorbance of the new solution would be different because the color of the solution would be different. There would also be a different molarity, so using this complex instead of another would not affect the experiments observations....
