Experiment 6 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

Affecting the Copper Mining Industry As is demonstrated by the chart below‚ the demand for copper has exceeded the supply brought to market since 2009. In 2011‚ 16.5 million tonnes of copper were produced worldwide and this amount is expected to grow by approximately 3% annually. Data from the International Copper Study Group (ICSG) for 2012 suggests that international demand for refined copper is expected to exceed production by about 240‚000 metric tons. The slow growth forecasted in copper supply is

Percentage of Copper in a Brass Alloy Assignment: G620 Sample Assignment C Date Set: Due Date: Assessment Objective(s): AO3 Vocational Brief: Brass is an alloy of copper and zinc. This alloy has many uses ranging from coinage to non-ferrous fittings on ships. Many domestic taps use brass where contact with water occurs. You are provided with a sample of brass which is about 150 years old and you are asked to quantitatively analyse it‚ using colorimetry‚ to find the percentage of copper present

In order to find the formula of the copper chloride hydrate‚ we had to separate the compound to find the mass of water and copper. To begin this process‚ we evaporated the water and created an anhydrous compound‚ meaning we were left with only CuxCly. By calculating the weight of both the anhydrous and the hydrated compounds‚ we could conclude that the difference in the weights was the weight of the H2O. From this we were able to calculate the percent composition of CuxCly and H2O (see Calculations:
