the solid copper(II) nitrate is used to dissolve in a test tube filled with half distilled water. The solid copper(II) nitrate ionize in water to form copper(II) ions and nitrate ion. Hence‚ a blue solution is formed due to the blue copper(II) ion present in the solution. When excess solid is added‚ the solution will become saturated and do not allow any solid to dissolve‚ so excess solid will remain in the solution. This is shows that the equilibrium between solid and aqueous copper(II) nitrate

EXTRACTION OF COPPER FROM OXIDISED COPPER ORE Aim: To analyse how copper is obtained from oxidised copper ore using the processes of leaching‚ solid-liquid separation‚ displacing and electrowinning. Method: Refer to ‘Extraction of Copper from oxidised Copper Ore’ document pages 1-2 Results: Leaching: The blue particles in the copper ore which is copper was dissolved in the sulphuric acid and the solution turned into a blue colour. There was also sediment that was floating around

Copper was the first metal that is used by humans as weapons and tools. It is shinny and has a reddish brown color. It’s application toward humans has really changed the way we live. Copper is an excellent conductor of electricity‚ which is often used as electrical wires or cables in generators‚ motors and electric products. In addition‚ it is also an outstanding conductor of heat‚ which is used in radiators and heating systems. Since it does not react with water and corrode easily‚ it is widely

Objects that are made from silver or coated with it‚ by time‚ start to tarnish. Tarnish is s chemical process that leads to dullness of color of the surface of the metals such as silver‚ gold‚ aluminum‚ iron‚ brass and copper. This reaction mostly happens because of the air pollution and/or moisture. To remove the tarnish from the metals‚ the silver objects must undergo a chemical reaction. Thus this chemical reaction would make the silver object look shiner. The chemical reaction to clean up the

Experiment 1: Synthesis of Copper Compounds Introduction This experiment involves the synthesis of compounds originating from pure solid copper. By applying solubility rules and the reactive properties of substances‚ many compounds which would otherwise be costly to extract from nature are able to be synthesized in the laboratory. Laboratory synthesized may sometimes be more economical than natural extraction‚ however it poses its own problems with the amount of substance that is actually yielded

Final Paper – A Silver Dish by Saul Bellow In chaos theory‚ the butterfly effect is a term used to describe how such irrelevant details can drastically change future events. The butterfly effect is a way of describing how‚ unless all other factors can be accounted for‚ large systems such as weather remains impossible to predict with total accuracy because of the countless unknown variables. Any complicated system may be vulnerable to drastic change due to small details being added or erased
