Limiting equivalent ionic conductivity table
Nettet29. mar. 2007 · In this work, we were interested to investigate whether it is possible to use a relationship between Δλ and Δr for metal halides to determine ionic radius values of Na + and F − in aqueous solution. Δλ is the difference in the limiting equivalent conductivities between the anion and the cation, whereas Δr is the difference in ionic radius. Nettet16. okt. 2024 · The equivalent conductivity of an ion in solution is derived by multiplying the equivalent conductivity of the entire electrolyte, Λ, by the ion’s transport number.Λ is obtained directly from the specific conductivity, S, but a better way of converting S to Λ is through σ i, the specific conductivity of ion i.Redefined to include the contribution of …
