I'm currently plotting some graphs of Activity coefficient against the root of Ionic strength and I have a couple of questions about the graph that I'm not quite sure on. (See graph PNG attached).

1. Does the limiting law plot seem accurate? I assume this is indicating that the LiCl measurement was made at higher concentrations than the law allows hence the large deviation from the prediction.

2. Why is Lithium growing in Activity as I increases? I was always told the rule of thumb is that they're inversely proportional?

Any help is appreciated.

Your plot is outside the scope of the Debye-Hückel limiting law.

Oh wild I just released I was given root I already I didn't need to root it again
That's put in the required region thanks again.

It does not matter - root or not - this is rather range of Davies equation.
