Explain the role of a salt bridge in an electrochemical cell.
Solution 25Q :
An electrochemical cell is a device that produces energy using chemical reactions such as redox reactions or it facilitates chemical reactions through the introduction of electrical energy. This device is also known as single galvanic cell.
An electrochemical cell consists of 2 half cells and each half cell comprises of an electrode which might be anode or a cathode and an electrolyte which can be of same type or different type in the half cells and these half cells are connected via a salt bridge.
