Expert Solution

In 1923, a Danish chemist, named Johannes Bronsted, and British scientist, Thomas Lowry, both independently proposed a different definition of acid. They said that an acid should be any substance that can donate a proton. In this case, a proton is just a hydrogen atom that has lost its electron to become a positively charged ion of H+. This definition of an acid is now called a Bronsted-Lowry acid.

Conjugate acid: an acid that forms when a base gains a proton.
Conjugate base: a base that forms when an acid loses a proton.
HCl + NH₃ --->NH₄⁺+CI^-
Acid₁ Base₂ Acid₂ Base₁
In this reaction, HCl donates proton toNH₃ & is therefore an acid. on the other hand, NH3 accepts a proton from HCl & is therefore a base. In the reverse reaction which at equilibrium proceeds at the same rate as the forward reaction, the NH₄+ ion donates a protons to CI^- ion & hence NH₄+is an acid,while Cl- ion which accept a proton from NH₄+ is a base.
