WebIn the reaction between two ions, the rate constant is k when the ionic strength (I) is 0.004. And the rate constant is k when the activity coefficient is 1. The ration k/k 0.884. If the charge of one ion is +1, the charge of other ion is close to (Debye-Hückel constant = 0.509 at 298K; log 0.884 = -0.05) दो आयनों के ... The ionic strength of a solution is a measure of the concentration of ions in that solution. Ionic compounds, when dissolved in water, dissociate into ions. The total electrolyte concentration in solution will affect important properties such as the dissociation constant or the solubility of different salts. One … Meer weergeven The molar ionic strength, I, of a solution is a function of the concentration of all ions present in that solution. $${\displaystyle I={\begin{matrix}{\frac {1}{2}}\end{matrix}}\sum _{i=1}^{n}c_{i}z_{i}^{2}}$$ where one half is because we are including both Meer weergeven • Activity (chemistry) • Activity coefficient • Bromley equation • Davies equation • Debye–Hückel equation Meer weergeven Because in non-ideal solutions volumes are no longer strictly additive it is often preferable to work with molality b (mol/kg of H2O) rather … Meer weergeven The ionic strength plays a central role in the Debye–Hückel theory that describes the strong deviations from ideality typically encountered in ionic solutions.
