Interpretation:
The purpose of salt bridge in voltaic cell has to be identified. The way how it completes its purpose has to be determined.
Concept Introduction:
An
Galvanic cell consists of two half-cells. The redox reaction occurs in these half-cells. The half-cell in which the reduction reaction occurs is known as the reduction half-cell, whereas the half-cell in which the oxidation reaction occurs is known as the oxidation half-cell.
The electrons flow from anode to cathode through the external wire of the circuit. A salt bridge is used to complete the cell circuit.
Anode: The electrode where the oxidation occurs is called as an anode. It is a negatively charged electrode.
Cathode: The electrode where reduction occurs is called as a cathode. It is a positively charged electrode.
Redox reaction: Redox reaction is a type of
The electric potential applied onto an electrode determines whether it hosts a reduction or oxidation reaction.
