2/12/2014, · ,Ion, exchange (IX) is a reversible reaction in which a charged ,ion, in a solution is exchanged with a similarly charged ,ion, which is electrostatically attached to an immobile solid particle. The most common implementation of ,ion, exchange method in ,wastewater, treatment is for softening, where polyvalent cations (e.g., calcium and magnesium) are exchanged with sodium [ 36 ].

To further define these substances, Arrhenius determined in 1884 that an acid will release a hydrogen ,ion, (H+) as it dissolves in water, and a base will release a hydroxyl ,ion, (OH-) in water ⁴. However, there are some substances that fit the operational definition (altering pH), without fitting the Arrhenius definition (releasing an ,ion,).

Ion, exchange reactions are stoichiometric and reversible, and in that way they are similar to other solution phase reactions. For example: NiSO4 + Ca (OH)2 = Ni (OH)2 + CaSO4. In this reaction, the nickel ions of the nickel sulfate (NiSO4) are exchanged for the …

When more of one ion is added to the solution, the concentration of the other decreases. The following equation describes this relationship: [H+] [OH-] = 1 x 10-14 (mol/L)2 = K W The product of the hydrogen and hydroxide ions is always equal to 1 x 10-14 (mol/L)2. Therefore, if the concentration of one ion increases by a factor of 10, then the concentration

Equation, 1 uses sodium chloride (NaCl) as an example. These reactions are most complete when the pH of the effluent from either resin is nearer the neutral mark. Since the cation reaction produces an ,acidic, effluent and the anion is more of a neutralization reaction, the anion reaction is the more complete.

Together with the equation defining K a, there are now three equations in three unknowns. When an acid is dissolved in water C A = C H = C a, the concentration of the acid, so [A] = [H]. After some further algebraic manipulation an equation in the hydrogen ion concentration may be obtained.
