Question

Molar conductance at infinite dilution of Ti(NO3)2, H2SO4 and HNO3 solution in water are a, b and c respectively. Molar conductance of TiSO4 solution at infinite dilution is
a – b + c
a + ab + c
a + b – 2 c
a – b + 2 c

Answer 1

Given:

Molar conductance at infinite dilution of Ti(NO3)2, H2SO4 and HNO3 solution in water are a, b and c respectively.

To find:

Molar conductance of TiSO4 solution at infinite dilution?

Calculation:

The molar conductance for $TiSO_{4}$ can be written as :

$\rm(\land_{\infty}^{\circ})_{TiSO_{4}} = (\land_{\infty}^{\circ})_{Ti(NO_{3})_{2}} + (\land_{\infty}^{\circ})_{H_{2}SO_{4}} - 2 (\land_{\infty}^{\circ})_{HNO_{3}}$

$\rm \implies (\land_{\infty}^{\circ})_{TiSO_{4}} = a + b - 2c$

So, the final answer is:

$\boxed{ \bf(\land_{\infty}^{\circ})_{TiSO_{4}} = a + b - 2c}$

• The usefulness of this method is that: It can be used to calculate the molar conductivity for a compound with the values of related compounds.

Hope It Helps.
