Question

Molar conductance of Bacl2 H2so4 and HCl at infinite dilutions are x1,x2,x3,respectively. Equivalent conductance of baso4 at infinite dilutions Will be?

Answer 1

Answer:

The answer is  x1 +x2 -2x3.

Explanation:

BaCl2 +  H2SO4 -----> 2HCl + BaSO4

Molar conductance at infinite dilution - H2SO4 = x2

                                                              BaCl2 = x1

                                                               HCl   =  x3

For two moles of HCl                            ( 2HCl = 2x3)

We know that  

BaSO4 = H2SO4 +BaCl2 - 2HCl

So with the help of above equation we can write  

Molar conductance of BaSO4 at infinite dilution is = x1 +x2 -2x3
