Correct option is B)

Aluminium is extracted by electrolytic reduction method. In electro-refining method, impure metal is taken as anode and pure metal is made of cathode. The electrodes are placed in acidified aqueous solution of metal salt or molten metal salt. On electrolysis, the metal in anode dissolves into the solution and gets deposited over the cathode. The residue left below the anode in the electro-refining of metal is called anode mud. Aluminum metal obtained by the electrolysis of fuse alumina is about 99.5% pure. It can be further refined by Hooper's electrolytic process.

Name one metal each which is extracted by:

(a) reduction with carbon. (b) electrolytic reduction.

(c) reduction with aluminium (d) reduction with heat alone.

Open in App Solution

Let us name one metal in each of the following cases:

(a) Reduction with carbon: Zinc is a moderately reactive metal and thus, its oxide is reduced by carbon.

(b) Electrolytic reduction: Sodium is a highly reactive metal and it cannot be reduced by carbon or aluminium. Thus, it is reduced by electrolysis.

(c) Reduction with aluminium: Manganese is a reactive metal and it cannot be reduced by carbon. Thus, it is reduced by aluminium.

(d) Reduction with heat alone: Mercury is a least reactive metal and thus, it is reduced on heating alone

Hint- Electrolytic reduction method is a process used in extraction of less reactive metals. They are reduced at cathode by accepting electrons & get deposited, we can also use this process for electroplating. Or we say It is the method of reducing metals by the process of electrolysis.

Complete answer:

Electrolytic reduction:

In this method of electrolysis electric current is passed through the molten state of metal ores. Metal; being positively charged; is deposited over the cathode (It is the method of reducing metals with the help of electrolysis).

The electrolytic reduction is a type of electrolysis. The oxides, hydroxide and chlorides of metals in fused state are electrically reduced by using this method. The metals are extracted at the cathode.

Some metals like Na, K, Mg, Ca, are obtained by this process. This method assures purity of metals obtained.

Highly electropositive metals Na,K,Ca,Al and Mg are extracted by electrolytic reduction. Au and Ag metals are extracted by hydrometallurgy

While Cu is extracted by pyrometallurgy.

Thus, from the given option:

We say Aluminium is extracted by electrolytic reduction method. In electro-refining method, impure metal is taken as anode and pure metal is made of cathode. The electrodes are placed in acidified aqueous solution of metal salt or molten metal salt. On electrolysis, the metal in anode dissolves into the solution and gets deposited over the cathode. The residue left below the anode in the electro-refining of metal is called anode mud. Aluminum metal obtained by the electrolysis of fused alumina is about 99.5% pure. It can be further refined by Hooper's electrolytic process.

Thus, we conclude aluminum metal is extracted by a given method.

Therefore, option (B) is the correct answer.

Note- Always remember that the Metals obtained from the process of electrolytic reduction are pure in form. And we say overall information which we learn from this question is that the method used to extract metals from the ore in which they are found depends on their reactivity.
