Electric Triple Layer Theory

I correct hundred years old theory of charge distribution within an electrolytic solution surrounded by charged walls. Existing theory always implies excess amount of counter-ions (having polarity unlike walls) everywhere in the solution domain; so it cannot handle a solution that possesses excess ions of other type (co-ions) or is electrically neutral as a whole. Here, in the corrected distribution, counter-ions dominate near the walls, while the rest of the domain is allowed to be dominated by co-ions; the algebraic sum gives the net charge present, which can be of any sign and magnitude that makes theory quite general. This clarifies and raises many important concepts: a novel concept of ‘Electric Triple Layer’ (ETL) replaces ‘Electric Double Layer’ (EDL) theory; widths of electric layers can be calculated accurately instead of estimating by Debye length scale etc. PACS numbers: 41.20.Cv, 82.45.-h, 82.60.Lf, 82.70.-y c © Copyright: reserved by Rajib Chakraborty ∗ Communication address: 89/3 Tanupukur Road, Dhakuria, Calcutta 700 031, West Bengal, India;
