The resistance of decinormal solution of...

The resistance of decinormal solution of a salt occupying a volume between two platinum electrodes `1.80 cm` apart and `5.4 cm^(2)` area was found to be `32 ohm`. Calculate `k` and `wedge _(eq)`.

Text Solution

Verified by Experts

Given `R=32 ohm, l=1.80 cm, a =5.4 cm^(2)`
`k=(1)/(R)xx(l)/(a)=(1)/(32)xx(1.8)/(5.4)=0.01041Sm^(-1)`
`wedge_(eq)=(kxx1000)/(N)=(0.01041xx1000)/(0.1)=104.1 S cm^(-2)` eq^(-1)`
