Zn(s)/Zn+2(aq)1M ||Cu+2(aq) 1M/Cu is representation of reaction in
Correct answer: C. Voltaic cell
- A. Daniel cell
- B. Down's cell
- C. Voltaic cell
- D. Nelson's cell
Explanation
The correct option for the reaction represented by Zn(s)/Zn²⁺(aq) 1M || Cu²⁺(aq) 1M/Cu is:Voltaic cell. Also known as a galvanic cell, it converts chemical energy into electrical energy. It spontaneously generates a current by utilizing the difference in electrode potentials of two half-cell reactions.Representation of the cell:Zn(s)/Zn²⁺(aq) 1M represents the left half-cell, where zinc metal (Zn) acts as the anode and loses electrons to become Zn²⁺ ions in the solution.Cu²⁺(aq) 1M/Cu represents the right half-cell, where copper ions (Cu²⁺) from the solution accept electrons at the cathode to become copper metal (Cu).The double vertical lines (||) signify a salt bridge or porous membrane separating the two half-cells, allowing ion mobility while minimizing direct mixing of solutions.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
