Respuesta :
Answer: The option (B) is correct.
Explanation:
According to Bronsted-Lowry acid base theory:
Bronsted-Lowry acids are those chemical species which are hydrogen ion donors
Bronsted-Lowry bases are those chemical species which are hydrogen ion acceptors.
[tex]NH_3+H_2O\rightarrow NH_4^++OH^-[/tex]
Here, ammonia is a Bronsted-Lowry base and water is a Bronsted-Lowry acid. [tex]NH_4^+[/tex] and [tex]OH^-[/tex] are conjugate acid and conjugate base respectively.
So,from the given options, option (B) is the correct answer.
