Title: Preparation of bis(acetylacetonato)copper(II) complex Objective: To synthesize the bis(acetyacetonato) copper(II) complex Theory/Background: All metal ions in solution are ’associated’ with water. The water molecules can also be weakly bonded or more strongly as a ligand to form a complex ion‚ and these can also present in solid ’hydrated’ salts of crystallization. E.g Copper(II) nitrate (Cu(NO3) 2.3H2O). A complex ion has a metal ion at its centre with a number of other molecules

results and theory relevant during an engineering experiment called “cold rolling of metals". The purpose of this report is to show how readings obtained from the set-out experiment‚ can be evaluated to determine the behavior of 3 selected materials; Brass‚ Copper and Aluminium through the process of cold rolling. The form of the materials are in small strips which are processed via cold-rolling method 4 times from their original state to evaluate the effects incurred on hardness values‚ width‚ length
