Bases can dissociate in water to release ions other than hydroxide. For example, sodamide (NaNH2) releases sodium cations and anionic amide ions (NH2-). Only salts containing hydroxide dissociate to release hydroxide ions (i.e. NaOH).
However, the released ion can then react with water to form hydroxide ions. In the case of sodamide, the amide ion reacts with water to produce ammonia and hydroxide ions. Note that the hydroxide is not formed directly by dissociation of the salt, but in a subsequent acid-base reaction.
When acids dissociate, they release hydrogen ions (H+). This process increases the concentration of H+ ions in the solution, making it acidic.
When bases dissociate in an aqueous solution, they release hydroxide ions (OH-) and the conjugate acid of the base. The process of dissociation increases the concentration of hydroxide ions in the solution, making it basic.
The strength of an acid or base is determined by its ability to donate or accept protons. In general, strong acids completely dissociate in water to release protons, while strong bases completely dissociate to release hydroxide ions. Weak acids and bases only partially dissociate, resulting in lower concentrations of protons or hydroxide ions in solution.
Arrhenius defined bases as substances that dissolve in water to release hydroxide ions (OH-) into solution.
Sodium hydroxide is highly basic, as it is a strong alkali. It can dissociate in water to release hydroxide ions, resulting in a high pH level.

Arrhenius defined bases as substances that dissolve in water to release hydroxide ions (OH-) into solution.
A compound that releases hydroxide ions (OH⁻) in solution, resulting in a pH greater than seven, is known as a base. Common examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH). These compounds dissociate in water, increasing the concentration of hydroxide ions and leading to an alkaline environment.
Sodium hydroxide is highly basic, as it is a strong alkali. It can dissociate in water to release hydroxide ions, resulting in a high pH level.
An acid contains more hydrogen ions than hydroxide ions. Acids release hydrogen ions (H+) in water, while bases release hydroxide ions (OH-).
