Question

The molar conductivities at infinite dilution of $K C l, K N O_{3}$ and $A g N O_{3}$ at $298 K$ are $0.01499 m h o m^{2} m o l^{- 1}, 0.01250 m h o m^{2} m o l^{- 1}$ and $0.01334 m h o m^{2} m o l^{- 1}$ respectively. What is the molar conductivity of $A g C l$ infinite dilution at this temperature?

Open in App

Solution

we have,
$K C l + A g N O_{3}$ $\to$ $K N O_{3} + A g C l$

molar conductivity of reactant = molar conductivity of product
0.01499 + 0.013344 = 0.01250 + molar conductivity of $A g C l$

molar conductivity of $A g C l$ = 0.0158 $m h o m^{2} m o l^{- 1}$
