Electrolytes and electrolysis Electrolysis
Reactive metals are extracted from their ores using electrolysis Ionic compounds conduct electricity when molten or in solution Metal ions and nonmetal ions are attracted to opposite electrodesA metal ore is a rock that contains enough of the metal to make it worthwhile extracting They have to be extracted from their ores through processes such as electrolysis, using a blast furnace or by reacting with more reactive material In many cases the ore is an oxide of the metal, therefore the extraction of these metals is a reductionExtracting Metals (413) | Edexcel GCSE Chemistry Revision Notes
