What is bronsted lowry acid base theory
Answers
A Brønsted-Lowry acid is any species that is capable of donating a proton—\text{H}^+H

A Brønsted-Lowry base is any species that is capable of accepting a proton, which requires a lone pair of electrons to bond to the \text{H}^+H

Water is amphoteric, which means it can act as both a Brønsted-Lowry acid and a Brønsted-Lowry base.
Strong acids and bases ionize completely in aqueous solution, while weak acids and bases ionize only partially.
The conjugate base of a Brønsted-Lowry acid is the species formed after an acid donates a proton. The conjugate acid of a Brønsted-Lowry base is the species formed after a base accepts a proton.
The two species in a conjugate acid-base pair have the same molecular formula except the acid has an extra \text H^+H

H, start superscript, plus, end superscript compared to the conjugate base.
According to the Bronsted-Lowry acid base theory any compound that is capable of transferring the fruit to any other compound is called as an acid and the compound which readily accepts that Proton transfer day is known as a base.
Further, this theory states that compound can only act as an acid in the presence of a base and similarly a compound can act as a base only in the presence of an acid.
When an acidic substance loses proton it becomes a conjugate base and when a basic substance gains a Proton it forms a conjugate acid.
This theory was independently proposed in the year 1923 by a Danish chemist named Johannes Nicolaus bronsted and an English chemist named Thomas Martin lowry.
