Answer :
Answer: The correct answer is Option 1.
Explanation:
Electrochemical cell is defined as the device that is used for the conversion of the chemical energy produced in a redox reaction into the electrical energy. In this cell, oxidation reaction occurs at anode and reduction reaction occurs at cathode.
For the given options:
Option 1: Oxidation reaction
Oxidation reaction is defined as the chemical reaction where a substance looses its electrons. The oxidation state of this substance gets increased and the substance gets oxidized.
[tex]X\rightarrow X^{n+}+ne^-[/tex]
Option 2: Reduction reaction
Reduction reaction is defined as the chemical reaction where a substance gains electrons. The oxidation state of this substance gets reduced and the substance gets reduced.
[tex]X^{n+}+ne^-\rightarrow X[/tex]
Option 3: Neutralization reaction
Neutralization reaction is defined as the chemical reaction where an acid reacts with a base to produce a salt and water molecule.
[tex]HX+BOH\rightarrow BX+H_2O[/tex]
Option 4: Transmutation
This is defined as the process in which a nucleus is converted to another nucleus.
From the above information, at anode, oxidation reaction occurs. Thus, the correct answer is option 1.
