Conductivity of 2 M KCL

(1/3) > >>

hi,

I thought it would be an easy task to find an answer, but after hours of searching I couldn't find more information that what CRC handbook can offer (reliable information). Conductivity of KCL in 15% mass percent solution at 20C is 208 mS/cm, but I think KCL is not yet saturated at that point. Anyone could help me on this?

Borek:
I am not sure what you are asking, what saturation has to do with the question?

2M solution is about 13.7%, for most practical applications just assuming linear dependence between conductivity at 15% and 13.7% is enough to get a reasonably accurate estimate.

hi,

I am asking what is the conductivity of 2 M KCL solution? CRC handbook ends at 15%, but I think 20% of KCL is still possible. And 25%, but probably not much higher than that...
I don't mind finding an answer in mass percent or mole weight. I am trying to find a conductivity value that is higher than 1M or 15% (those ones I know).

Borek:
As I already wrote: 2M solution is 13.7%, you don't need tables going up to 20%.

15% KCl solution is 2.2M.

dalav24:
And the question is still about conductivity. The unit of the questions is S.
Conductivity of 15% KCL at 20C is 208 mS/cm. How about 2 M, 3 M, 20% or 25%?
