WebMar 30, 2024 · The Cu 2+ solution was mixed with Gly solution in 1:1 molar ratio. Figure 5 shows the UV-Vis absorption spectra for the control (DI H 2 O), free copper sulfate solution (Cu 2+) and Cu 2+ :Gly solution in 1:1 ratio after 60 minutes equilibrium time. WebPrepare cis- [Cu (gly)2 (OH2)] as follows: a. Dissolve 3.0 grams of CuSO45H2O in 35 mL of water in a 100-150 mL conical flask. b. To this solution add 2.0 g of glycine with stirring. c. Warm (ca. 50°C) and stir the mixture for 15 minutes. d. Cool the solution to room temperature then add 11 mL of 2.5 M NaOH.

WebThe results showed that they have similar decomposition process, which occur in two steps. The first step is the loss of water and the second step is the decomposition of anhydrous … WebThe thermal decomposition reactions of the complexes cis/trans - [Cu (gly) 2] • H 2 O were studied by TG-DSC methods. The results showed that they have similar decomposition process, which occur in two steps. The first step is the loss of water and the second step is the decomposition of anhydrous complexes. Webcis-Cu (gly)2 · H 2 O Copper (II) acetate monohydrate (0.01 mole, 2.0 g) is dissolved in 25 cm 3 of hot water. 25 cm 3 of hot ethanol is added and the solution kept hot. Glycine (0.02 mole, 1.5 g) is dissolved in 25 cm 3 of hot water. The solutions are mixed while hot (~70C) and the solution then cooled on ice. mercy springfield mo cno
