The molar conductivities Lambda(NaOAc)^@...

The molar conductivities `Lambda_(NaOAc)^@` and `Lambda_(HCI)^@` at infinite dilution is watter at `25^@C` are `91.0` and `426.2 S cm^@ //`mol respectively. To calculate `Lambda_(HOAc,)^2` the additional value required is:

A

`Lambda_(H_2O)^o`

B

`Lamda_(KCI)^o`

C

`Lambda_(N_aOH)^o`

D

`Lambda_(NaCI)^o`

Text Solution

Verified by Experts

The correct Answer is:

D

According to Kohlrausch 's law ,
`Lambda_(CH_3COOH)^@ = Lambda_(CH_3COONa)^@ + Lambda_(HCI)^2- Lambda_(NaCI)^@`.
