Aqueous solutions dissociation

For example, a monobasic reagent HR dissociates in aqueous solution (dissociation constant ) and is distributed between the organic and aqueous phases (distribution coefficient/fDR). Thus... [Pg.56]

As remarked in Sidebar 3.11, soluble salts MA (M = cation, A = anion) often behave as strong electrolytes in aqueous solutions, dissociating completely into ionic species as expressed by... [Pg.112]

In water and aqueous solutions, dissociation and ionization take place... [Pg.9]

Strong acids in aqueous solution dissociate completely into anions and protons. The concentration of hydrogen ion [H+] is therefore equal to the total concentration CHA of the acid HA that is added to the solution. Thus the pH of the solution of a strong acid is simply —log CHa-... [Pg.52]

You know that ions are present in an aqueous solution of an acid. These ions result from the dissociation of the acid. An acid that dissociates completely into ions in water is called a strong acid. For example, hydrochloric acid is a strong acid. All the molecules of hydrochloric acid in an aqueous solution dissociate into H+ and Cl ions. The H+ ions, as you know, bond with surrounding water molecules to form hydronium ions, H30+. (See Figure 10.6.) The concentration of hydronium ions in a dilute solution of a strong acid is equal to the concentration of the acid. Thus, a 1.0 mol/L solution of hydrochloric acid contains 1.0 mol/L of hydronium ions. Table 10.4 lists the strong acids. [Pg.381]

From the time of his first paper on the coordination theory in 1893 30, 98), Werner had been aware of the role of the solvent in electrolytic dissociation and had insisted that hydration, i.e., aquation, preceded ionization. In his paper, Zur Theorie der Basen" (1907) 91), he applied this concept to his new definition of a base Any compound, which with water forms a hydrate which dissociates in aqueous solution into a complex positive ion and hydroxyl ions, is an anhydro base.. . . Aquo bases, or simply bases, are water addition compounds which in aqueous solution dissociate into hydroxyl ions." For example ... [Pg.58]

Like the aqueous solution of HCI you saw in Figure 10-11, sodium hydroxide (NaOH) in an aqueous solution dissociates into its ions sodium (Na+) and hydroxide (OH ). Copper chloride (CUCI2) also dissociates into its ions,... [Pg.293]

In aqueous solution, dissociation of the salt to Cl and C HsNHj is complete. The weak acid C6H5NH3 dissociates as follows ... [Pg.247]

Like other acids, phosphoric acid in aqueous solutions dissociates into ions according to... [Pg.214]

Carbonic acid in aqueous solutions dissociates to form the bicarbonate ion (hCO and a hydrogen ion (H+). [Pg.744]

The principal components that make rainwater acidic are nitric and sulfuric acids, which are strong acids. Each molecule oi strong acid or strong base in aqueous solution dissociates completely to provide one molecule of or OH . Nitric acid is a strong acid, so the reaction... [Pg.175]

The situation changes completely when the dissolved chains are polyelectrolytes rather than electrically neutral macromolecules. Polyelectrolytes in a, usually aqueous, - solution dissociate in polyions with fixed positive or negative charges and mobile counter-ions. The arising Coulomb forces are much stronger than the van der Waals forces and result in quite unusual solution properties. [Pg.70]

Problem For the cell reaction of hydrogen gas and chlorine gas to produce HCl in aqueous solution (dissociated into ions), how does temperature affect the cell voltage given that the standard state molar entropy for the products is 56.3 J moH ... [Pg.157]

The water molecule acts as a base in an aqueous solution, dissociation constant... [Pg.432]
