Why is electrolysis only used to extract certain metals?
Electrolysis is mainly used for extracting metals that are highly reactive and difficult to obtain by other methods. These metals typically have a strong affinity for electrons, making them suitable candidates for the reduction process involved in electrolysis. Metals like sodium, potassium, and aluminum are commonly extracted using electrolysis because of their high reactivity.
What metals aren't suitable to be used as pipes?
