Raw kerosene used as coolant tends to dissociate and polymerize. A substance may dissociate without necessarily producing ions. Upon dissolution in acid, potassium bitartrate will dissociate into acid tartrate, tartrate, and potassium ions. Ionic compounds, when dissolved in water, dissociate into ions. These ionic compounds dissociate completely in water. Chaotropic salts that dissociate in solution exert chaotropic effects via different mechanisms. Strong electrolytes are hypothesized to dissociate completely in solution. Unlike molecular compounds, salts dissociate in solution into anionic and cationic components. The cation bonded with the latter anion will dissociate and bond with the other anion. ADP and P do not dissociate until ammonia binds and glutamine is released. At physiologic pH, chlorhexidine salts dissociate and release the positively charged chlorhexidine cation. These compounds dissociate near the hot center of the lamp, releasing isolated dysprosium atoms. Tetraalkylated ammonium hydroxides are also strong bases since they dissociate completely in water. Conjugate pairs dissociate into separate spermatozoa before fertilization. Ultraviolet light is blocked before it can dissociate water into hydrogen and oxygen.
