WebIonic Strength Calculator I = Ionic Strength ; ci = concentration of the ith ion ; zi = Charge of the ith ion -- Ionic strength of a solution indicates the concentration of ionic charge in the solution. Activity coefficient of an ionic solution is related to the ionic strength of the solution by Debye-Huckel formula. Cite Discuss WebThe ionic strength is I = 1/2 Σ c z 2, where c and z are the concentration and valence of the ith ion in the solution ( Robinson and Stokes, 1970 ). To calculate I for the ADP-binding assay solutions, it is necessary to have appropriate pK a -values for imidazoleH +, H 2 EDTA 2−, and TrisH +.
