Calcium hydroxide has been widely used as intra canal medicament because of its anti microbial action, ionic dissociation
, high pH and enzyme inhibiting activity [8 99 10].
(8) conducted a study to evaluate the rate of ionic dissociation
of calcium hydroxide associated to different vehicles--aqueous, viscous, and oily--and concluded that aqueous and viscous vehicles are better suited for paste use.
The new method combines two different ionic dissociation
methods, collision induced dissociation (CID) and electron capture dissociation (ECD), to analyze proteins thoroughly by quickly switching the dissociation methods.
In 1884 Arrhenius presented his theory of ionic dissociation
as his Ph.D.
After the notion of ionic dissociation
was established by Arrhenius, an acid came to be defined as a substance that split up to yield hydrogen ions, while a base was one that split up to yield hydroxyl ions (OH;s-).
Arrhenius had assumed this when he had worked out his theory of ionic dissociation
two years earlier (see 1884).
Arrhenius's theory of ionic dissociation
(see 1884) made it look as though atoms or groups of atoms could carry electric charges.
