Considering the Brönsted- Lowry Theory, the products formed in this Brønsted-Lowry reaction is:
- NO₂⁻: conjugated base of HNO₂
- H₂SO₄: conjugate acid of HSO₄⁻
According to the Brönsted- Lowry Theory, acids and bases can be defined as follows:
- An acid is a species that donates an proton H⁺.
- A base is a chemical species that accepts a proton H⁺ from acid.
So, according to this theory, the reactions between acids and bases are H⁺ proton transfer reactions:
Acid + Base ↔ Conjugate Base + Conjugate Acid
where:
- Conjugate base: ion or molecule resulting from the acid that loses the proton
- Conjugated acid: ion or molecule resulting from the base that gains the proton
In this case, you have the balanced reaction:
HNO₂ + HSO₄⁻ → NO₂⁻ + H₂SO₄
So, considering all previous, you have:
- HNO₂: acts as a acid because it is capable of yielding a proton H⁺
- HSO₄⁻: acts as an base because it will accept a proton H⁺ from HNO₂
- NO₂⁻: conjugated base of HNO₂
- H₂SO₄: conjugate acid of HSO₄⁻
Finally, the products formed in this Brønsted-Lowry reaction is:
- NO₂⁻: conjugated base of HNO₂
- H₂SO₄: conjugate acid of HSO₄⁻
