What is debye huckel equation?

Debye-Huckel equation is an equation for calculating the activity coefficients of electrolyte solutions. It was developed independently by Peter Debye and Erich Huckel in the early 20th century to describe the behavior of electrolyte solutions at low concentrations and high dilutions. The equation takes into account the effects of the charges and sizes of ions on the activity coefficients. The equation is based on two assumptions, that the electrolyte solution is a perfect mixture and that the ions in the solution are spherical in shape. The equation has been widely used in physical and analytical chemistry, biochemistry, and geochemistry for predicting the behavior of electrolyte solutions in different environments. The equation can be applied to a variety of solutions, including aqueous solutions, nonaqueous solutions, and mixtures of solvents. The Debye-Huckel equation has been modified over time to include more accurate factors that may affect ion behavior, such as temperature and pressure.
