Debye-Hückel limiting law

The Debye-Hückel limiting law describes how the electrical activity of ions in a dilute solution decreases due to their mutual interactions. In simple terms, when ions are spread out in a solution, they attract or repel each other, affecting their behavior as if they were isolated. The law quantifies this effect, showing that at low concentrations, ions deviate from ideal behavior in a predictable way, making calculations of their activity (effective concentration) more accurate. It provides a fundamental understanding of how ions influence each other in dilute electrolytes, crucial for fields like chemistry and electrochemistry.
