- Copper chloride dihydrate (1.7g) and triphenylphosphine Ph3P (4g) are reacted together to form what complex and what would be the theoretical yield with the complex? Explain the chemistry which occurs in the experiment.Explain the procedure for synthesis of transition metal complexes of hydroxycinnamic acids? For the synthesis of complexes of transition metals with substituted hydroxycinnamic acids, to be specific, p-coumaric acid and ferulic acidWhy is the pH of the medium important for the formation of chelated complexes between metal ions and ligands? Choose the best answer: Select one: a. Because the ligands give rise to acid-base reactions that influence the stability of the chelate b. Because if the pH is not very acidic, the ligands do not protonate and the complex cannot form c. Because the pH of the medium is always important for any type of reaction. d. Because in the absence of pH there is no reaction of any kind

Explain the chemistry behind the synthesis.Explain the three factors that can act in the substitution reactions ofoctahedral complexes: solvent, ionic pair and conjugated base. Indicate techniques experimental data that could be used to verify such actions.You are assigned an unknown solution that contains Group III cations. To -1 mL of this solution was added 6 M NH3 the solution was agitated to mix well, and a reddish-brown precipitate with a gelatinous solid clinging to the inner walls of the test tube was observed. The solution was centrifuged and the supernatant was tested for completeness of precipitation by adding an additional drop of 6 M NH3. No cloudiness was observed as the drop of reagent diffused through the solution. The supernatant was then carefully decanted into a clean test tube, labeled (1st solution), and saved for further testing later. The precipitate remaining in the test tube was washed with a small amount of water, centrifuged, and the wash decanted and discarded. To the precipitate was added about 10 drops of 6 M NAOH plus ~1 mL H20 and the test tube was vigorously agitated. The resulting suspension was centrifuged and the supernatant liquid was transferred to another clean test tube and clearly labeled (2nd…
