Which of the following ions is commonly used in a salt bridge? (2020)

Step 1: Understand what a salt bridge is. A salt bridge is a device used in electrochemical cells to connect two half-cells.
Step 2: Know the purpose of a salt bridge. It helps maintain electrical neutrality by allowing ions to flow between the half-cells.
Step 3: Identify common ions used in salt bridges. Potassium ions (K+) are one of the most commonly used ions.
Step 4: Remember that potassium ions help balance the charge in the electrochemical cell.
