Question

Write the anme of the cell which is generally used in transistors. Write the reactions taking place at the anode and the cathode of this cell.

Answer 1

Dry cell is generaly used in transistors.
Reaction of cell taking place at anode and cathode are:
At anode: `Zn(S)toZn^(2+)+2e^(-)`
At cathode: `2MnO_(2)(S)+2NH_(4)^(+)+2e^(-)toMn_(2)O_(3)(S)+2NH_(3)(g)+H_(2)O`
