Question

Guess the reason why highly reactive metals like k na ca ma are extracted by electrolysis of their fused salts only

Answer 1

Answer:

Metals more reactive than carbon, such as aluminium, are extracted by electrolysis, while metals less reactive than carbon, such as iron, may be extracted by reduction with carbon. As gold is so unreactive, it is found as the native metal and not as a compound. It does not need to be chemically separated.
