Prelab assignment
**Ethylenediamine should be abbreviated "en". ** **Tris (etheylenediamine) nickel (H) chloride should be abbreviated "Ni (en) 3Cl2". ** 1. Describe a Lewis acid and Lewis base. A Lewis acid is usually a Cat ion that accepts electron from an unshared one. While Lewis base is a nucleophilic and more often an Anion that donates a lone-pair of electrons (Leach, 1999). 2. Using the reaction to be performed in this lab, determine the limiting reactant if 1.3 g NiCl2.6H2O and 11 ml 1.4 M ethylenediamine are reacted. Since it has less ethylenediamine required to react all of the NiCl2.6H20, then ethylenediamine ...
