The molar conductivity of KCl solutions at different concentrations at 298K are given below: Show that a plot between Lamda_(m) and c^((1//2)) is a straight line. Determine the values of Lamda_(m)^(@) and A for KCl. |
Answer» Solution :Taking the square root of concentration, we obtain:  Graph of `lamda_(m)=sqrt(c) ` vs `c^(1//2)` is as GIVEN below:  It is nearly a straight line. A=slope=-87.46 S `cm^(2)mol^(-1)("mol "L^(-1))^(1//2)` From the intercept `(c^(1//2)=0)`, we find that `Lamda_(m)^(@)=150.0" S "cm^(2)mol^(-1)`. |
