At certain temperature and infinite dilution , the equivalent conductances of sodium benzoate , hydrochloric acid , and sodium chloride are 240 , 349 and `229 Omega^(-1) cm^(2) eq^(-1)` respectively . The equivalent conductance of benzoic acid in `Omega^(-1) cm^(2) eq^(-1)` at the same condition is

A

80

B

328

C

360

D

408

Text Solution

Verified by Experts

The correct Answer is:
C
`Lambda_(C_(6)H_(5) COOH)^(@) = Lambda_(C_(6)H_(5) COONa)^(@) + Lambda_(HCl)^(@) - Lambda_(NaCl)^(@)`
`Lambda_(C_(6)H_(5) COOH)^(@) = 240 + 349 - 229`
`Lambda_(C_(6)H_(5) COOH)^(@) = 240 + 349 - 229`
`Lambda_(C_(6)H_(5)COOH)^(@) = 360 Omega^(-1) cm^(2) eq^(-1)`
