Which of the following represents the sequence of Brønsted-Lowry acids and bases in the following equilibrium? CH3COOH + NH3 CH3COO- + NH4+

Respuesta :


it is A). acid + base  base + acid

Answer:

Acetic acid is acting as Brønsted-Lowry acid.

Ammonia is acting as Brønsted-Lowry base.

Explanation:

According to Brønsted-Lowry acids concept:

Acids are those chemical compounds which donates proton to other compound and forms conjugate base.

Bases are those chemical compounds which accepts proton from other compounds and form conjugate acids.

[tex]CH_3COOH(Acid) + NH_3(base)\rightarrow CH_3COO^-(\text{conjugate base}) + NH_{4}^{+}(\text{conjugate acid})[/tex]

Acetic acid on donation of [tex]H^+[/tex] ion forms acetate ion which means it is acting as Brønsted-Lowry acid and whereas in products acetate ion[tex]CH_3COO^-[/tex] is conjugate base.

Ammonia by accepting [tex]H^+[/tex] ion forms ammonium ion which means it is acting as Brønsted-Lowry base and where as in product ammonium [tex]NH_4^+[/tex] is a conjugate acid..
