Question

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

Answer 1

it is A). acid + base base + acid

Answer 2

Acetic acid is acting as Brønsted-Lowry acid.

Ammonia is acting as Brønsted-Lowry base.

Step-by-step 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.

`CH_3COOH(Acid) + NH_3(base)\rightarrow CH_3COO^-(\text{conjugate base}) + NH_(4)^(+)(\text{conjugate acid})`

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

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