Final answer:
The Debye-Huckel quantitative treatment is a mathematical approach to ion activity in solution. It explains the incomplete ionization of strong electrolytes by considering the residual attractions between ions.
Step-by-step explanation:
The Debye-Huckel quantitative treatment is a mathematical approach to ion activity in solution. In 1923, chemists Peter Debye and Erich Hückel proposed a theory to explain the apparent incomplete ionization of strong electrolytes. They suggested that interionic attraction in an aqueous solution is reduced by solvation of the ions and the insulating action of the polar solvent, but not completely nullified. The residual attractions prevent the ions from behaving as totally independent particles.
