The equivalent conductances at infinite ...

The equivalent conductances at infinite dilution `(A_(0))` for electrolytes BA and CA are 140 and 120 S `cm^(2)`/eg. For equivalent conductance at infinite dilution for BX is 198 S `cm^(2)` /eg. The `A_(0)` ( in S `cm^(2)//eq`) of CX is

A

178

B

198

C

218

D

130

Text Solution

Verified by Experts

The correct Answer is:
A
`Lambda^(@) (CX) = lambda_(C)^(@) + lambda_(X)^(@)`
` = Lambda^(@) (BX ) + Lambda^(@) (CA) - Lambda^(@) (BA)`
`= 198 + 120 - 140= 178 S cm^(2) eq^(-1)` .

The molar conductance at infinite dilution for electrolytes BA and CA are 140 and 120 ohm^(-1) Cm^(2) mol^(-1) respectively. If the molar conductance at infinite dilution of BX is 198 ohm^(-1) cm^(2) mol(-1), then then at infinite dilution, the molar conductance of is:

At infinite dilution, when the dissociation of electrolyte is complete, each ion makes a definite contribution towards the molar conductance of electrolyte, irrespective of the nature of the other ion with which it is associated. the molar conductance of an electrolyte at infinite dilution can be expressed as the sum of the contributions from its individual ions. A_(x)B_(y) rarr xA^(y+)+yB^(x-) Lambda_(m)^(@)(A_(x)B_(y))=xlambda_(A^(y+))^(@)+ylambda_(B^(x-))^(@) where, x and y are the number of cations and anions respectively.
