Question

what is an electrochemical or galvanic cell ? Explain the construction And working of galvanic cell.​

Answer 1

➠ AnSwer :-

• A galvanic cell is an electrochemical cell that converts the chemical energy of a spontaneous redox reaction into electrical energy.

$⟹$Construction :-

• 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.

$⟹$Working :-

• During a redox reaction, a galvanic cell utilizes the energy transfer between electrons to convert chemical energy into electric energy.
• A galvanic cell can be made out of any two metals.
• These two metals can form the anode and the cathode if left in contact with each other.

Answer 2

° Galvanic Cell :--

                           → A galvanic cell is an electrochemical cell that converts chemical energy of a spontaneous redox reaction into electrical energy .

# Functions :-

• Spontaneous then ΔG = -ve .

• In this device ΔG of spontaneous redox reaction is converted into electrical work ( which may be used for running a motor, fan, heater, etc. ) .

# Construction :-

                           → It consist of two mettalic electrodes dipping in electrolytic solution.

                               

                                  → The solution in two compartment is connected through an inverted U shaped tube containing a mixture of agar -agar jelly and an electrolyte like KCl, $KNO_{3}$, etc. .

Hope this will help you ;)
