Question
A conductivity cell filled with a 0.01 M KCl solution was found to have a resistance of 189 ohms at 25oC. When filled with 0.01 M HCl solution, the cell gave a resistance of 64.8 ohms at the same temperature. At 25oC, the conductivity of 0.01 M KCl solution was 1.4088 x 10-3 S cm-1.
Calculate (a) the cell constant and (b) the conductivity of the HCl solution.
answer is [0.266; 4.105 x 10-3]
