Which of the following metals are obtained by electrolysis of their chlorides in molten state ?
(i) Na (ii) Ca (iii) Fe (iv) Cu
(A) (i) and (iv)
(B) (iii) and (iv)
(C) (i) and (iii)
(D) (i) and (ii)
Metals like Na and Ca are able to produce ions in their molten state . Therefore, they can be obtained from their chlorides in molten state.
So, the correct answer is (d)
