Voltaic cell can be converted into a reverse galvanic cell by?
Correct answer: D. All of these options are correct
- A. Changing the the positions of electrodes
- B. Replacing the salt bridge with a wire
- C. Providing an external source of electricity
- D. All of these options are correct
Explanation
The correct option is: All of these options are correct. A voltaic cell can be converted into a reverse galvanic cell by doing any or all of the following: Changing the positions of electrodes: In a voltaic cell, the electron flow is spontaneous from the anode to the cathode. By swapping the positions of the anode and cathode, the electron flow will be reversed, making it a reverse galvanic cell Replacing the salt bridge with a wire: In a voltaic cell, the salt bridge is used to maintain charge neutrality by allowing the movement of ions between the half-cells. By replacing the salt bridge with a conducting wire, the ions' movement is hindered, and the cell functions as a reverse galvanic cell. Providing an external source of electricity: In a voltaic cell, the chemical reactions at the electrodes create an electric potential difference that drives the flow of electrons. If you provide an external source of electricity (e.g., a battery or power supply) and apply a potential in the opposite direction, it will force the cell to function in reverse, becoming a reverse galvanic cell. So, all of the options mentioned can convert a voltaic cell into a reverse galvanic cell.

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.
