what is an electrochemical or galvanic cell ? Explain the construction And working of galvanic cell.
Answers
Answer:
A galvanic cell or voltaic cell, named after Luigi Galvani or Alessandro Volta, respectively, is an electrochemical cell that derives electrical energy from spontaneous redox reactions taking place within the cell.

Answer:
Galvanic cell:
A galvanic cell is an electrochemical cell that converts the chemical energy of a spontaneous
redox reaction into electrical energy.
Galvanic cell is made up of two half cells i.e., anodic and cathodic. The cell reaction is of redox kind. Oxidation takes place at anode and reduction at cathode. It is also known as voltaic cell. It may be represented as shown in Fig. Zinc rod immersed in ZnSO4 behaves as anode and copper rod immersed in CuSO4 behaves a cathode.
In this device, the Gibbs energy of the spontaneous redox reaction is converted into electrical work which may be used for running motor or other electrical gadgets like heater, fan, geyser,etc.The following redox reaction occurs in Galvanic cell,
Zn(s) + Cu2+ (aq) Zn?+ + (aq) Cu(s)
