Bronsted-Lowry Theory Acids and Bases | Conjugate acid & Base | Amphoteric Compounds| Limitations

In this fully Animated Lecture you will learn about Bronsted-Lowry Theory of Acids and Bases.
In 1923. the Danish chemist Bronsted and the English chemist Lowry independently presented their theories, of acids and bases that are based on, proton-transfer.
According to this concept:
An acid is a substance. that can donate H positive ion to another substance. on the other hand.
A base is a substance, that can accept H positive ion from, another substance.
it can also be defined as an acid that donates a proton, while a base is a substance that accepts a proton.
what exactly is a proton?
An atom of hydrogen contains 1 proton, 1 electron. When hydrogen loses an electron to become H+ ion. only a proton remains so H + ion is also known as proton. Therefore, in simpler terms, a proton is a hydrogen ion without its electrons.
Bronsted-Lowry theory does have its limitations.
It has been observed that, there are certain substances. which behave as acids. however, they do not have the ability to donate protons.
for example. sulphur dioxide behaves as an acid. but it cannot donate a proton. Similarly, calcium oxide behaves as a base. but, it cannot accept a proton. These observations prove limitations of the Bronsted-Lowry concept, of acids and bases.
