Preparing copper sulfate | edexcel Core Practical

Excess copper oxide must be added to warm dilute sulfuric acid (warmed using a water bath), which will react to produce a blue solution of the salt copper(II) sulfate. The solution then needs to be filtered using filter paper and evaporated using an evaporating basin and Bunsen burner, followed by final drying using a watch glass to allow all the water to …

Leaching of copper oxide with different acid solutions

The effect of temperature on the rate of copper dissolution from CuO when leached in the three inorganic acids was investigated over a temperature range of 30–50 °C at acid concentration of 0.5 M, stirring speed of 400 rpm and l/s = 10 ml/g. Fig. 5 shows that temperature has a significant effect on the acceleration of copper dissolution with HNO …

COPPER

Copper(I) complexes. Forming copper(I) complexes (other than the one with water as a ligand) also stabalises the copper(I) oxidation state. For example, both [Cu(NH 3) 2] + and [CuCl 2]-are copper(I) complexes which don't disproportionate. The chlorine-containing complex is formed if copper(I) oxide is dissolved in concentrated hydrochloric acid.
