In an Ni-Cd battery – InterviewSolution

1.	In an Ni-Cd battery
Answer» all the REACTANT and products in the overall reaction are in the solid state The voltage of the CELL changes repidly the electrolyte used is an `NaCl` solution all the above are true. Solution :The NICKEL-cadmium cell (nicad cell) is a com-mon storage BATTERY. It is a voltaic cell consisting of an anode of cadmimum and a cathode of hydrated nickel oxide (approximately `NiOOH`) on nicke, the electrolyte is potes-sium hydroxide. To see why a nicad battery produces a constant voltage, we can write the Nernst equation for its reaction and look at `Q`. No gaseous substance is involved.
