Given the redox reaction in an electrochemical cell:

Ni(s) + Pb2+(aq) + Ni2+(aq) + Pb(s)

A salt bridge is used to connect

A) Ni(s) and Pb(s)

B) Pb2+(aq) and Ni2+(aq)

C) Ni(s) and Ni2+(aq)

D) Pb2+(aq) and Pb(s)

Please help me

Pb2+(aq) and Ni2+ B

Explanation:A salt bridge is a laboratory device used in an electrochemical cell  to connect the oxidation ( which occurs at the anode ) and reduction( which occurs at the cathode) half-cells of a galvanic cell voltaic cell, It prevents the cell from quickly  reaching equilibrium  by maintaining  electrical charge  neutrality within the internal circuit because the electrons are moving from one-half cell to the other.

In this electrochemical cell,  Ni (s) is oxidized to Ni2+(aq) and will occurs at the anode while  Pb2+(aq) is reduced to Pb (s) and will occur at the  cathode.

false

because it does not have the potential to be entirely used up
