Answer:
1. HSO³⁻(aq) + H₂O(l) → H₂SO₃(aq) + OH⁻(aq)
<u>The Brønsted-Lowry acid is H₂O and the Brønsted-Lowry base is HSO³⁻</u>
<u />
2. (CH₃)₃N(g) + BCl₃(g) → (CH₃)₃NBCl₃(s)
<u>There are no Brønsted-Lowry acids and bases in this reaction.</u>
Explanation:
According to the Brønsted-Lowry concept, when an acid (HA) and a base (B) undergoes a chemical reaction, the acid (HA) loses a proton and forms its conjugate base (A⁻), whereas the base gains (B) the proton to form its conjugate acid (HB⁺).
<em>The chemical equation for this reaction is:</em>
HA + B ⇌ A⁻ + HB⁺
Given reactions:
1. HSO³⁻(aq) + H₂O(l) → H₂SO₃(aq) + OH⁻(aq)
<u>The Brønsted-Lowry acid is H₂O and the Brønsted-Lowry base is HSO³⁻</u>
Reason: In this reaction, the acid H₂O loses a proton and forms its conjugate base, OH⁻. Whereas, the base HSO³⁻ gains a proton to form its conjugate acid, H₂SO₃.
2. (CH₃)₃N(g) + BCl₃(g) → (CH₃)₃NBCl₃(s)
<u>There are no Brønsted-Lowry acids and bases in this reaction.</u>
Reason: In this reaction, there is no exchange of proton between the acid and the base.
