Although an improvement was made to the Debye–Hückel equation in 1926 by Lars Onsager, the theory is still regarded as a major forward step in our understanding of electrolytic solutions.
Selvom Debye-Hückel-ligningen i 1926 blev forbedret af Lars Onsager, regnes denne teori stadig for at være et stort skridt i mod vores forståelse af elektrolytopløsninger.
