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

`^^_(H_(2)O)^(0)`

B

`^^_(KCl)^(0)`

C

`^^_(NaOH)^(0)`

D

`^^_(NaCl)^(0)`

Text Solution

Verified by Experts

The correct Answer is:
D
`CH_(3)COONa+HCltoCH_(3)COOH+NaCl`" From the reaction"`
`overset(0)^^CH_(3)COONa+overset(0)(^^)_(HCl)=overset(0)(^^)_(CH_(3))COOH+overset(0)(^^)_(NaCl)oroverset(0)(^^)_(CH_(3)COOH)=overset(0)(^^)_(CH_(3)COONa)+overset(0)(^^)_(HCl)-overset(0)(^^)_(NaCl)`
Thus to calculate the value of `overset(0)(^^)CH_(3)COOH` one should know know the value of `overset(0)(^^)_(NaCl)` along with `overset(0)(^^)_(CH_(3)COONa)` and `overset(0)(^^)_(HCl^(-))`
