For extraction of sodium from `NaC1`, the electrolytic mixture `Nac1+Na_(3)A1F_(6) +Cac1_(2)` is used. During extractions process, only sodium is deposited in cathpode but `K` and `Ca` do not because

A

Na is more reactive than K and Ca

B

Na is less reactive than K and Ca

C

NaCl is less stable than `Na_(3)AIF_(6)` and `CaCl_(2)`

D

the discharge potential of `Na^(+)` is less than that of `K^(+)` and `Ca^(+2)` ions

During extraction of metals, electrolytic refining is used to obtain pure metals. During the process, the impure metal is made the anode and a thin strip of pure metal is made the cathode. The solution of the metal salt is used as an electrolyte. On passing the current through the electrolyte, the pure metal from the anode dissolves from the electrolyte. An equivalent of pure metal from the electrolyte is deposited on the cathode. Which of the metals are refined by electrolytic refining? I. Au II. Cu III. Na IV. K
