# Electrical conductivity and the limits of Kohlrausch's law

I am currently writing a lab report on electrical conductance and I realized that my partner prepared $$\pu{0.1 M}$$ solution instead of $$\pu{0.01 M}$$. Now, I am supposed to find the molar conductivity of the solution at infinite dilution. Although the data gathered fits beautifully in the regression, the value found for $$\Lambda_0$$ is wrong. What is the best way to explain that? By saying that at such concentrations, the effects $$\sqrt{c}$$ become negligible and are and not having enough steps in the data between a concentration in solution of $$\pu{0-0.01 M}$$ induces a big error on our value ? Or is there something else/better to do ?

• Could you describe the experiment in more detail? I'm assuming that you started with a stock solution of 0.1 molar and created various dilutions from that. An overview of your mathematical analysis is necessary too. – MaxW Feb 7 at 14:21
