Question

Which metal can be obtained by electrolytic reduction of their

molten ores? (i) Na (ii) K (iii) Al (iv) All of these
​

Answer 1

Answer:

Aluminum

Explanation:

Aluminum is extracted by electrolytic reduction methodelectro-refining method, impure metal is taken as anode and pure metal is made of cathode.

Answer 2

Answer:

Oᴘᴛɪᴏɴ iv) Aʟʟ ᴏғ ᴛʜᴇsᴇ

ᗰOᖇᗴ TO KᑎOᗯ :-

Metals such as K, Na, Ca, Mg and Al, that are reactive or at the top of the electrochemical series, are extracted from the electrolysis of fused compounds.In case of their aqueous solutions, metals cannot be extracted as the water in the solution gets discharged at the cathode and only electrolysis of fused compounds is possible. These fused compounds are generally chlorides.
