A base that partly dissociates in solution is called a weak base. This means it only partially ionizes in water, resulting in a lower concentration of hydroxide ions compared to a strong base which fully dissociates.
Acid + base salt + water
When a strong base dissociates in water, it releases hydroxide ions (OH-) into the solution. This results in an increase in pH and the formation of a basic solution. Common examples of strong bases include sodium hydroxide (NaOH) and potassium hydroxide (KOH).
A base that only partly ionizes in a solution is considered a weak base. This means that only a small fraction of the base molecules will ionize to release hydroxide ions in the solution. Examples of weak bases include ammonia (NH3) and methylamine (CH3NH2).
An inorganic base dissociates in water to release hydroxide (OH-) ions. This process increases the concentration of hydroxide ions in the solution, leading to an alkaline pH.
A weak base dissociates partially in water to form the conjugate acid and hydroxide ions. The dissociation is characterized by a low degree of ionization, resulting in a small concentration of hydroxide ions in solution.
