One Hundred Years of Ghosh’s Strong Electrolyte Theory

Abnormal behaviour of strong electrolytes was a hot research topic around the turn of twentieth century. In 1918, J. C. Ghosh published a series of articles dealing with this abnormal behaviour and suggested a cube ischolar_main law for data correlation. The publications were both praised and criticised. Debye and Huckel published in 1923 their well-known theory of strong electrolytes, the square ischolar_main law, which completely overshadowed Ghosh’s theory. By the middle of twentieth century, however, Ghosh’s theory became prominent again, particularly for concentrated electrolyte solutions, in the light of pseudo-lattice theory of strong electrolytes. In this article, we discuss some features and historical developments of Ghosh’s theory to commemorate its centenary year.
