What is the difference between a strong base and a weak base?

Hint: We know that the Bronsted–Lowry theory, also known as the proton theory of acids and bases, is a theory proposed by the Danish chemist Johannes Nicolas Brønsted and the English chemist Thomas Martin Lowry in \[1923.\] It states that any compound that can transfer a proton to another compound is an acid, and any compound that accepts the proton is a base.

Complete answer:
To understand the difference between a strong base versus a weak base with regards to ionization Let's look at the Bronsted-Lowry concept of acids and bases. : To solve such questions write the symbol of cation on the left side and write its charge just below it. Similarly write the symbol of anion on the right side and its charge below it.
A material can only act as an acid in the presence of a base, and a substance can only function as a base in the presence of an acid, according to the Bronsted–Lowry system. Furthermore, when an acidic substance lacks a proton, it forms a base known as an acid's conjugate base, and when a basic substance gains a proton, it forms an acid known as a base's conjugate acid.
A strong base is a base that ionizes or dissociates almost \[100%\] in water to form \[O{{H}^{-}}\] ion. An example of a strong base is sodium hydroxide. It dissociates in water to form sodium ions and hydroxide ions. A weak base is a base that ionizes or dissociates only partially in water to form \[O{{H}^{-}}\] ion. An example of it will be ammonia. It only dissociates partially to form ammonium hydroxide.

Note:
Remember that the charge on the anion will be equal to the number of atoms of cation and charge of cation will be equal to the number of atoms of anion. Combining all these things we will get the chemical formula of the desired compound. Also remember to reduce the molecules to the smallest integer.
