A weak base is a base that, upon dissolution in water, does not dissociate completely, so that the resulting aqueous solution contains only a small proportion of hydroxide ions and the concerned basic radical, and a large proportion of undissociated molecules of the base.
30 mar 2019 · Definition: A weak base is a base that is partially dissociated in an aqueous solution. Examples: NH 4 OH. Cite this Article. Here is the definition of a "weak base" as the term is used in chemistry, along with examples of weak bases.
Weak bases are the basic substances that do not completely ionize in water. An example of a weak base is ammonia. When NH 3 is dissolved in water, a part of it dissociates into ammonium cation and hydroxide anions by interacting with the water molecules.
A weak base is a chemical species that has the ability to accept a proton (H+) in an aqueous solution, forming a conjugate acid-base pair. Weak bases are less likely to completely ionize compared to strong bases, and their degree of ionization is dependent on the pH of the solution.
A weak base is one that does not completely dissociate into its ions in water.
This page explains the terms strong and weak as applied to bases. As a part of this it defines and explains K b and pK b. We are going to use the Bronsted-Lowry definition of a base as a substance which accepts hydrogen ions (protons).
A weak base is a type of base that only partially dissociates in an aqueous solution, producing a relatively low concentration of hydroxide ions. This is in contrast to strong bases, which completely dissociate in water, producing a high concentration of hydroxide ions.
