Derive a relationship between dissociation constant K_(a) and molar conductivity wedge_(m).

Answer»

Solution :According to Ostwald dilution Law,
`""K_(a)=(alpha^(2)C)/((1-alpha))"...(1)"`
SUBSTITUTE a VALUE in the above expression (1)
`""K_(a)=(wedge_(m)^(2)C)/(wedge_(m)^(2)(1-wedge_(m)/(wedge_(m)^(@))))`
`""K_(a)=(wedge_(m)^(2)C)/(wedge_(m)^(2)(wedge_(m)^(@)-wedge_(m))/wedge_(m)^(@))`
`RARR K_(a)=(wedge_(m)^(2)C)/(wedge_(m)^(@)(wedge_(m)^(@)-wedge_(m)))`.
