Basics of solubility and Solubility Products
Basics of solubility and Solubility Products

The solubility of a sparingly soluble salt of a ,weak acid, or base will depend on the pH of the solution. To understand the reason for this, consider a hypothetical salt MA which dissolves to form a cation M + and an anion A – which is also the conjugate base of a ,weak acid, HA.

Factors To Consider In Wastewater - 1
Factors To Consider In Wastewater - 1

Most natural water, domestic wastewater and many industrial wastewater are buffered by a carbon dioxide-bicarbonate system. Acid waters are of concern because of their corrosive characteristics and the expense involved in removing or controlling the corrosion-producing substances.

One ,weak acid, not removed is carbonic ,acid,, produced by the cation exchange of an alkaline salt, as illus- trated by the following equation employing sodium bicarbonate: RH + NaHC03 = RNa + H2C03 H2C03 = H20 + C02 The carbon dioxide produced is unaffected by the ,weak, base anion exchange resin: the gas is readily eliminated through established technology with aeration or degasification.
