Ion flow in salt bridge

WebThe salt bridge is a key component of any voltaic or galvanic electrochemical cell. Typically, it is a tube filled with electrolytic solutions such as potassium chloride (KCl) or other chlorides. The bridge serves the purpose of keeping the cell electrically neutral and allowing the free flow of ions through its entirety, which prevents electron build-up in the half … WebIdentify the ion flow in the salt bridge. Negative ions in the salt bridge will migrate towards the oxidation half -reaction and positive charge builds up in the cell. Positive ions will migrate towards the red uction half-cell as positive charge is removed from the half -cell, leaving a net negative charge in this half -cell that will attract ...
