Question

NICKEL (II) The reaction with DMG gives: [Ni(DMG)212 (aq) The reaction with HCl gives: [NiClg(aq) The reaction with ethylenediamine gives: [Ni(en)al2(aq) The reaction with NaOH gives: Ni(OH)2(s) The reaction with EDTA gives: [NIEDTA]2(ag) Write a balanced equation for each reaction. How many d electrons are there in Ni2* For each complex ion formed, indicate the coordination number of the copper atom. Name each complex. Do your best to sketch a 3D representation of each Are isomers possible? If so, what are they? Record the observed color of each solution. What does this suggest about the wavelength of light absorbed for each? Use your observations to rank chloride ion, ethylenediamine and EDTA in the spectrochemical series. Which is a stronger field ligand? Explain your reasoning.
