Question

What is a Bronsted base?

Answer 1

Hint: The Bronsted – Lowry theory, also known as the proton theory of acids and bases states that any compound that is able to transfer a proton to another compound is categorized as an acid, where a proton is considered as a nuclear particle with a unit positive electrical charge.

Complete answer: - In the question it is asked what a Bronsted base is.
- According to the Bronsted – Lowry theory, the chemical species which donated electrons were identified as Bronsted bases. In other words, Bronsted bases are the species which have the ability to accept protons from outside.
- This theory is very important to a chemist because, with this theory, one can observe and understand the chemical reactions occurring between acids and bases.
- The compound that receives a proton is known as a base. Similarly, on losing a proton, an acidic substance forms a base called conjugate base of an acid while on gaining a proton, a basic substance forms an. Acid called the conjugate acid of base. Keeping this in mind, we should be able to solve the given question.
- It also shows how pH levels of various compounds are affected.
- The give and take of electrons took place between different species to attain a stable electronic configuration.

Note: The electronegativity of a chemical species is directly proportional to its acidic character. Similarly, as the electronegativity of a species decreases, the tendency for that species to donate electrons increases. Hence, electronegativity is inversely proportional to the basicity of the species.
