🔋 Gouy-Chapman-Stern Electric Double Layer

Visualize how ions arrange near a charged electrode into a rigid Stern layer and a diffuse Gouy-Chapman cloud, and see how electrolyte concentration reshapes the potential decay.

The simulation renders ion density and electrostatic potential near a charged electrode, showing the rigid Stern layer of adsorbed ions transitioning into the thermally broadened Gouy-Chapman diffuse layer.

🔬 What It Demonstrates

🎮 How to Use

Adjust electrolyte concentration and surface charge sliders to watch the Debye length compress or expand and to see the balance shift between the compact Stern layer and the diffuse ion cloud.

💡 Did You Know?

Doubling the electrolyte concentration in a simple 1:1 salt solution shrinks the Debye screening length by roughly a factor of 1.4, since it scales as the inverse square root of ionic strength.
