If a salt bridge is removed from two half cells the emf is:
Correct answer: C. Dropped to zero
- A. Increased
- B. Decreased
- C. Dropped to zero
- D. Electrodes will be reversed
Explanation
Salt bridge maintain the electrical neutrality between two half cells preventing net charge accumulation which will occur. Without the salt bridge, the electron flow will not happen inside the galvanic cell, so it will not be able to generate electricity or the electric current. And to the extent that it will stop the electrolysis process.If salt bridge is removed then emf will drop to zero.

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.
