Ion-Selective Membrane Function Explained | Electrochemistry Visualization #1952419 (License: Personal Use)

This educational diagram illustrates the selective permeability of a membrane-here allowing only protons (H⁺, red) to cross while restricting sodium (Na⁺, green) and chloride (Cl⁻, yellow) ions. The left panel shows the initial setup; the right panel depicts the result after ion migration, demonstrating electrochemical separation principles used in technologies like PEM fuel cells and desalination.

Used in science education, chemistry textbooks, or engineering resources to explain membrane-based ion transport; matches user intent for understanding selective diffusion, osmosis, or electrochemical cell operation.
