Question

i need help with this lab please. can i get someone to answer the entire thing. thank you

Instructor Equilibria of Coordination Compounds OBSERVATIONS AND DATA 1. The formation of complex ions with ammonia The net ionic equation for the reaction of excess Cuso, with NH, is 24 Cu2+ + 4NH3 [cu (NH3)4] The predicted effect on the reaction above of adding excess NH, (based on Le Châtelier's principle) is The reaction will shift to the night and product formation wil Describe the observed results when excess NH, is added to Cuso, solution: Precipitate dissolves and there is Coluche NH,Cl and Cuso, solutions are mixed: no Change in Solution excess NaOH and Cuso, solutions are mixed Blue precipitade is formed CuSO,.5H,0(s) is exposed to NH, gas: Deep blue color Considering the equilibrium equation NH,+H,0 = NH, +OH", explain which substance (NH, NH, or OH-) causes the deep blue color when ammonia is added to a copper(II) solution, and give the equation for the reaction The observed effect and the net ionic equation for the reaction of HNO, on this deep blue solution is 15 Lab Report: Equilibria of Coordination Compound
