Vedclass · Answer

(B) Highly reactive metals such as 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 by the electrolytic reduction of their molten chloride salts (e.g.,$NaCl$ and $CaCl_2$).Metals like Iron $(Fe)$ and Copper $(Cu)$ are less reactive and are typically extracted by reduction with carbon or other chemical methods.Thus,only $(i)$ and $(ii)$ are obtained by the electrolysis of their molten chlorides.

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