Question

Calculate the molar conductivity at infinite dilution of AgCl from the following data:
A°(AgNO3) = 13.34mSm-mol-1, 4°(KCI) = 14.99mSm-mol-4,1°(KNO3) = 13.34mSmềmol-1

Answer 1

Given:

A°(AgNO3) = 13.34mSm-mol-1,

A°(KCI) = 14.99mSm-mol-1,

A°(KNO3) = 13.34mSmềmol-1

To find:

Molar conductivity at infinite dilution of AgCl.

Solution:

The reaction will be:

KCl + AgNO3   → KNO3  +AgCl

As we know that:

molar conductivity of reactant = molar conductivity of product

14.99 + 13.34 = 13.34 +   molar conductivity of AgCl

molar conductivity of AgCl = 14.49 mSm-mol-1

Therefore the molar conductivity at infinite dilution of AgCl is 14.49 mAm-mol-1.
