Answer:
An acid is the specie which can donate a proton.
Explanation:
Bronsted lower acid:
An acid is the specie which can donate a proton.
Bronsted lower base:
A base is the specie that can accept the proton.
For example:
HCl + NH₃ → NH₄⁺ + Cl⁻
Here in this reaction HCl is act an acid because it donate the proton while NH₃ is Bronsted lower base because it accept the proton.
Bronsted lowery acid = proton donor
Bronsted lowery base = proton accepter
