Activity Coefficient Calculator (Debye-Hückel)
Calculate the mean activity coefficient (γ) of ions in dilute aqueous solutions using the Debye-Hückel limiting law.
Input Parameters
Instant Real-time CalculationIn non-ideal electrolyte solutions, electrostatic interactions reduce effective ion activity. The Debye-Huckel limiting law calculates the activity coefficient gamma for dilute solutions (I < 0.1 M).

Activity Coefficient Calculator (Debye-Hückel) — Frequently Asked Questions
Q1 Why is the activity coefficient less than 1.0? ▾
In electrolyte solutions, oppositely charged ions attract one another, forming an ionic atmosphere that shields individual ions and lowers their effective chemical activity below their actual concentration.
