In a Voltaic cell zinc electrode is dipped in:
Correct answer: D. Zinc sulphate
- A. Copper sulphate
- B. Copper chloride
- C. Zinc chloride
- D. Zinc sulphate
Explanation
One half -cell in a voltaic cell is constructed from a silver wire dipped in silver nitrate solution of unknown concentration. The other half cell consists of a zinc electrode in a solution of Z n ( N O 3 ) 2 .

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.
