A cell with cathode: Mg anode: Cu -> whats the purpose of the salt bridge with reference to the cell and explain ion movement
Anode: Positive Mg2+ formed (ox)
Cathode: Cu2+ destroyed (red)
Negative ions move through salt bridge to return charge to zero at the anode half-cell where Mg2+ are being formed.
Positive ions move through salt bridge to return charge to zero at the cathode half cell where Cu2+ are being destroyed and the solution would have been left with a negative charge
