1.	A conductivity cell is platinized toA. avoid temperature effectB. avoid capacitance of the cellC. avoid polarization effectD. prolonf its life
Answer» Correct Answer - C Electrodes of the cell are made of platinum and are coatedx freshly electrolytically with finely divided platinum black before use to minimize the polarization effect (i.e. change of resistance of solution near the electrodes due to change of concentration of electrolyte).
