1. Bi-Bivalent definition is - relating to or being an electrolyte that dissociates into two Bivalent ions.

2. This ammonia diffuses from the bloodstream into the fluid of the coelomic cavity, where it dissociates into ammonium ions.

3. The acid dissociation or ionization constant, Ka, is large, which means HCl dissociates or ionizes practically completely in water.

4. However, the acetylcholine does not remain bound; rather, it dissociates and is hydrolyzed by the enzyme, acetylcholinesterase, located in the synapse.

5. When carbon dioxide dissolves in water about one-percent of it forms Carbonic acid, which almost immediately dissociates to bicarbonate anions and protons

6. "When carbon dioxide dissolves in water about one-percent of it forms Carbonic acid, which almost immediately dissociates to bicarbonate anions and protons

7. Carbonic acid is a weak acid that is created when carbon dioxide (CO 2) is dissolved in water (H 2 O), resulting in the chemical formula H 2 CO 3.When the acid dissociates, or gives up a hydrogen ion, the resulting molecule is called a bicarbonate ion.
