Answer:
- Brønsted-Lowry acid: HNO₂
Explanation:
The equation is:
[tex]HNO_2(aq)+NH_3(aq)\rightarrow NH4^+(aq) + NO2^-(aq)[/tex]
Brønsted-Lowry acids are H⁺ donors.
Brønsted-Lowry bases are H⁺ acceptors.
Thus, on the left side, HNO₂ is the acid and NH₃ is the base.
The conjugate acids and conjugate bases are on the right side of the equation.
The conjugate acid is the spieces that is formed after a base accepts the proton; thus it is NH₄⁺. A conjugate acid contains one more H atom and one more + charge than the base that formed it.
The conjugate base is the species that is formed after the acid donates its proton; thus, NO₂⁻ is the conjugate base. A conjugate base contains one less H atom and one more - charge than the acid that formed it.
Summarizing:
- Brønsted-Lowry acid: HNO₂
