Salt bridge are used to give?
Correct answer: C. Both Options A and B are correct
- A. Highly conductive path
- B. To balance amount of negative and positive ions in both half-cells
- C. Both Options A and B are correct
- D. To increase resistivity
Explanation
OPTION A: The salt bridge is used in electrochemical cells to provide a highly conductive path between the two half-cells. OPTION B: The salt bridge is also used to balance the amount of negative and positive ions in both half-cells.OPTION C: A salt bridge refers to a device used to form an electrochemical cell by providing a means to support the free flow of ions between the Oxidation and reduction half-cell components. A salt bridge facilitates corrosion because corrosive reactions typically occur in the presence of electrochemical cells. OPTION D: Salt bridges are used to provide a highly conductive path and balance the charge between half-cells, not to increase resistivity.

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.
