Question

Give the construction and working of galvanic cell

Answer 1

Galvanic cell is the electrochemical cell which basically convert chemical energy into electrical energy .

It is also called as voltic cell .

cell obtained its electrical energy from redox reaction which is taking place within the cell

It's construction though very simple which constitutes anode (positive terminal ) cathode(negative terminal )

placed in the electrolytic solution (the cathode and anode should be of different metals )

Answer 2

$\huge\mathfrak\color{blue}{Answer}$

Electromotive Force (EMF) has been measured to be 1.100 V. A concentration of 1 M in an ideal solution is defined as the standard condition, and 1.100 V is thus the standard electromotive force, DEo, or standard cell potential for the Zn−Cu galvanic cell
