The molar conductanve at infinite dilution of `AgNO_(3),AgCl and NaCl ` are `116.5,121.6 and 110.3 Omega^(-1) cm^(2)" mole"^(-1)` respectively. The molar conductances of `NaNo_(3)` is:

A

`H^(+)` ions is much more than that of `Cl^(-)` ions

B

`Cl^(-)` ions is much more than that of `H^(+)` ions

C

`H^(+)` ions is much more than that of `Na^(+)` ions

D

`Na^(+)` ions is much more than that of `H^(+)` ions

Text Solution

Verified by Experts

The correct Answer is:
C
`^^_((aq))^(@)HClgtgtA^_(eq)^(@)(NaCl)`. Since `Cl^(-)` ions are common. This means their ionic conductance of `H^(+)gtgt` ionic conductance `prop` ionic mobility.
`lambda_("cation")propmu_("cation"),lambda_("anion")propmu_("anion")`
`therefore` H ions have much greater mobility than `Na^(+)` ion.
