`lambda_(ClCH_(2)COONa)=224 "ohm"^(-1) cm^(2) " gm eq"^(-1)`,
`lambda_(NaCl)=38.2 "ohm"^(-1) "cm"^(2) gm eq"^(-1)`.
`lambda_(HCl)=203 "ohm"^(-1) cm^(2) "gm eq"^(-1)`.
What is the value of `lambda_(ClCH_(2)COOH)` ?

A

`228.5 ohm^(-1) cm^(2) gm eq^(-1)`

B

`289.5 ohm^(-1) cm^(2) gm eq^(-1)`

C

`388.8 ohm^(-1) cm^(2) gm eq^(-1)`

D

`59.5 ohm^(-1) cm^(2) gm eq^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C
`Lambda (Cl CH_(2) COOH)`
`= Lambda (Cl CH_2 COONa) + Lambda (HCl) - Lambda(HCl) - Lambda (NaCl)`
`=224 + 203 - 38.2`
`= 388.8 ohm^(-1) cm^(2) "equiv"^(-1)`
