In a Voltaic Cell, a Zinc Electrode is dipped in?
Correct answer: D. Zinc Sulphate
- A. Copper Sulphate
- B. Copper chloride
- C. Zinc Chloride
- D. Zinc Sulphate
Explanation
Option A: Copper sulfate (CuSO4) is a compound that contains copper and sulfur. While copper sulfate is commonly used in various applications, including as a fungicide and in electroplating processes, it is not typically used as an electrolyte in a voltaic cell with a zinc electrode. Option B: Copper chloride (CuCl2) is another compound that contains copper and chlorine. Similar to copper sulfate, copper chloride is used in different applications, such as in the production of dyes, and catalysts, and as a flame colorant. However, it is not the preferred electrolyte for a voltaic cell with a zinc electrode. Option C: Zinc chloride (ZnCl2) is a compound that contains zinc and chlorine. While zinc chloride can be used as an electrolyte in certain battery systems, it is not commonly used as an electrolyte for a voltaic cell with a zinc electrode. Zinc chloride is more commonly utilized in applications like metal surface treatment, soldering fluxes, and some chemical reactions. Option D: In a voltaic cell, a zinc electrode is typically dipped in zinc sulfate (ZnSO4) solution. This solution acts as the electrolyte and facilitates the movement of ions in the cell. The other half-cell of the voltaic cell would contain a copper electrode dipped in a copper salt solution, such as copper sulfate (CuSO4), which completes the electrochemical reaction.

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.
