Here is the definition of a "weak base" as the term is used in chemistry, along with examples of weak bases.
An example of a weak base is ammonia. It does not contain hydroxide ions, but it reacts with water to produce ammonium ions and hydroxide ions. The position of equilibrium varies from base to base when a weak base reacts with water. The further to the left it is, the weaker the base.

Bases of carbon, nitrogen and oxygen without resonance stabilization are usually very strong, or superbases, which cannot exist in a water solution due to the acidity of water. Resonance stabilization, however, enables weaker bases such as carboxylates; for example, sodium acetate is a weak base. Strong bases
Weak Acid Definition. A weak acid is an acid that is partially dissociated into its ions in an aqueous solution or water. In contrast, a strong acid fully dissociates into its ions in water. The conjugate base of a weak acid is a weak base, while the conjugate acid of a weak base is a weak acid.
A base (weak or strong) can be defined as the following three types: Arrhenius, Bronsted Lowry, and a Lewis Base. Examples of weak bases include baking soda, ammonia, and antacid medicine.
These examples are from the Cambridge English Corpus and from sources on the web. Any opinions in the examples do not represent the opinion of the Cambridge Dictionary editors or of Cambridge University Press or its licensors. These reactions are generally run in the presence of a weak base, such as ...
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). Note: If you don't know what the Bronsted-Lowry theory is, you ...
Definition of a Strong Base. You may not realize it, but strong bases are everywhere! For one thing, they are incredibly effective cleaning agents; in fact, most of the cleaning agents in your ...
