The resistance of solution of a salt occupying a volume between two platinum electrode 1.8cm apart and 5.4cm^(2) in area was found to be 30 ohm. Calculate the conductivity of the solutions.

Answer»

Solution :RESISTANCE of a solution R=32ohm
DISTANCE between two electrodes =1=1.8cm
AREA of the electrode `A=5.4 cm^(2)`
FORMULA:
`"CONDUCTIVITY "=("Cell constant")/("Resistance")=(1.8)/(5.4)xx (1)/(32)=0.01404.Scm^(-1)`
