Why does the voltage drop to zero, when you remove the salt bridge in an electorchemical cell?

Answer 1

When the cell operates, one electrode (A) loses electrons, and they travel by wire to the other electrode (B).

At A, positive ions are released into the electrolyte solution.
This build up of positive charge tends to discourage electrons from leaving the electrode.

At B, the loss of positive ions (as they are oxidised) causes a build up of negative ions in the electrolyte there. This discourages electrons from travelling to electrode B.

The salt bridge between the two electrolyte solutions allows the ions to travel between electrolyte A and electrolyte B, neutralising the charges. If it is removed, the charge build up will cause the electron flow to slow, then stop, resulting in a zero voltage.

Answer 2

because of the fact to verify that the reaction to happen the two factors of the cellular could desire to be related. The salt bridge enables ions to pass in the two guidelines to maintain a independent universal value. removing the bridge in actuality shall we all the effective value development up on one and the damaging on the different, which will no longer produce any voltage.
