$(i)$ and $(ii)$

Vedclass · Answer

(B) Highly reactive metals like sodium $(Na)$ and calcium $(Ca)$ are placed at the top of the reactivity series.These metals have a very high affinity for oxygen and cannot be reduced by carbon or other common reducing agents.Therefore,they are extracted from their ores (usually chlorides) by the process of electrolytic reduction in the molten state.Sodium is obtained by the electrolysis of molten sodium chloride $(NaCl)$,and calcium is obtained by the electrolysis of molten calcium chloride $(CaCl_2)$.Iron $(Fe)$ and copper $(Cu)$ are less reactive and are typically extracted by reduction with carbon or by other metallurgical processes.Thus,the correct metals obtained by the electrolysis of their molten chlorides are $(i)$ and $(ii)$.

Which of the following metals are obtained by electrolysis of their chlorides in molten state?
$(i)$ $Na$
$(ii)$ $Ca$
$(iii)$ $Fe$
$(iv)$ $Cu$
