Question

Highly reactive metals are extracted by the process of :
A.Electrolysis
B.Reduction
C.Electroplating
D.None of the above

Answer 1

Hint: Electrolysis is a chemical reaction that occurs when an electric current is conducted through a material. When a material loses or acquires an electron, it is referred to as a chemical change (oxidation or reduction). An electrolytic cell is a device that consists of positive and negative electrodes that are kept apart and dipped in a solution containing positively and negatively charged ions.

Complete answer:
Electrolysis is a chemistry and industrial technology that employs direct electric current (DC) to drive a chemical reaction that would otherwise be non-spontaneous. Electrolysis is crucial in the industrial separation of elements from naturally occurring sources like ores using an electrolytic cell. The decomposition potential is the voltage required for electrolysis to occur. The word "lysis" means "to separate or break," thus electrolysis may be defined as "electrical breakdown" or "electrical breakdown."
Electrolytic reduction is used to remove high-reactivity metals from their ores, such as sodium, calcium, magnesium, and aluminium. Carbon is less reactive than these metals, thus it cannot be used to decrease them. A lump of impure metal and a thin strip of pure metal are dipped in the salt solution of the metal to be purified in the electrolytic refining process. Pure metal is coated over a narrow strip of pure metal when an electric current is conducted through the solution; from a lump of impure metal. Impure metal is utilised as the anode, whereas pure metal is employed as the cathode.
Hence option A is correct.

Note:
Electrolysis refers to the breaking apart from a molecule by the means of the electrochemical reaction. Electroplating refers to the passage of current through the solution with metal such that it gets deposited on one of the electrodes.
