The pH system is a scale that was developed in 1909 by the Danish scientist Soren Sorensen. On this scale, a solution is acidic when its pH is low, a solution is basic when its pH is high and solutions with a pH of 7 are neutral. The pH of a substance is calculated by using the following formula: pH = -log[H+]

Solubility Parameters: Theory and Appliion

The theory of solubility parameters is a constantly developing body of scientific concepts that can be of immense practical assistance to the conservator. Through the media of solubility maps, complex molecular interactions can be visualized and understood, and in this way, solubility theory can simply function as a ladder to be left behind once the basic concepts are …
