The interaction between colloids in polar mixtures above Tc
... The dashed and dashed-dotted curves in Fig. 1(a) are the same as the solid curve for τ = 0.008 except for one parameter. The effect of charge asymmetry is shown by the dasheddotted curve, where the total charge was kept constant, but σ L = 3σ R . Here the attraction is stronger, as in the classic Po ...

... In using the term mole for ionic substances, we mean the number of formula units of the substance. For example, a mole of sodium carbonate, Na2CO3 is a quantity containing 6.023 x 1023 Na2CO3 units. But each formula unit of Na2CO3 contains 2 x 6.023 x 1023 Na+ ions and one CO32ions and 1 x 6.023 x 1 ...

Electrochemistry
Electrochemistry is the branch of physical chemistry that studies chemical reactions which take place at the interface of an electrode, usually a solid metal or a semiconductor, and an ionic conductor, the electrolyte. These reactions involve electric charges moving between the electrodes and the electrolyte (or ionic species in a solution). Thus electrochemistry deals with the interaction between electrical energy and chemical change.When a chemical reaction is caused by an externally supplied current, as in electrolysis, or if an electric current is produced by a spontaneous chemical reaction as in a battery, it is called an electrochemical reaction. Chemical reactions where electrons are transferred directly between molecules and/or atoms are called oxidation-reduction or (redox) reactions. In general, electrochemistry describes the overall reactions when individual redox reactions are separate but connected by an external electric circuit and an intervening electrolyte.
