Is electrolysis in c1?Watch
Here's what's on the spec for c1 and electrolysis:
Metals that are more reactive than carbon, such as aluminium, are extracted by electrolysis of molten compounds. The use of large amounts of energy in the extraction of these metals makes them expensive.
Copper can be extracted from copper-rich ores by heating the ores in a furnace (smelting). The copper can be purified by electrolysis.
Copper can be obtained from solutions of copper salts by electrolysis or by displacement using scrap iron.
Candidates should know that during electrolysis positive ions move towards the negative electrode.
