The cell constant of a conductance cell is obtained by measuring

  • A.the resistance of the cell filled with air
  • B.a solution of known specific conductance
  • C.the distance between the electrodes with a scale
  • D.the conductance of distilled water

Answer: B

Standard potassium chloride solutions have tabulated specific conductance, and dividing that by the observed conductance gives the constant in reciprocal centimetres. Measuring the geometry directly is neither accurate nor practical.
