Identify the products formed in this Brønsted-Lowry reaction.
HSO4-, + HNO2, = acid + base


Sagot :

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⁻
