A series of free igcse chemistry activities and experiments (cambridge igcse chemistry) electrolysis of copper(ii) sulphate solution this experiment is designed to demonstrate the different products obtained when the electrolysis of copper(ii) sulfate solution is carried out first with inert graphite electrodes and then with copper electrodes.
Note: copper is an exception to the rules for writing electron configurations! video: cu cu and cu 2 electron configuration notation in writing the electron configuration for copper the first two electrons will go in the 1s orbital.
The reactivity series shows metals in order of reactivity the reactivity of a metal can be worked out by studying its reactions iron and aluminium are extracted from their ores in different ways.
This extraction experiment consists of two competition reactions a metal oxide is reacted with charcoal if the charcoal (carbon) is more reactive it will remove the oxygen from the metal oxide and leave a trace of metal in the reaction vessel start with an oxide of lead then observe what happens to an oxide of copper.
Extraction of copper chalcopyrite (cufes 2) is the commonest copper orecopper is mainly extracted from the sulphide ore (cu 2 s) by the self-reduction process the ores are often low grade (05% .
The principal ore of copper is copper pyrite and copper is extracted from this ore the different steps in extraction of copper are: crushing and concentration: the ore obtained from mines are broken down into small piece by jaw crusher and then pulverized the ore being sulphide ore is concentrated by froth floatation process.
Copper mining: the commonest ore used in the extraction of copper is chalcopyrite (cufes 2) also known as copper pyrites and other such sulphides the percentage of copper in the actual ore is too low for direct extraction of copper to be viable the concentration of ore is required and it is done by the froth flotation method concentration of .

Copper - from beginning to end copper is a major metal and an essential element used by man it is found in ore deposits around the world it is also the oldest metal known to man and was first discovered and used about 10000 years ago and as alloyed in bronze (copper-tin alloy) about 3000 bc was the first engineering material known to man.
Extraction of metals extraction of copper copper is sometimes found as native metal copper ores include copper(ii) oxide and copper(ii) sulfide copper(ii) oxide can be reduced by reaction with carbon some copper ores may contain only small amounts of copper these are called low grade ores and have less than 1% copper but they are still used because copper is so valuable.
