Question

In the following reactions identify which substances correspond to Arrhenius acids and bases and which to Brønsted - Lowry acids and bases

a. HBr → H+ + Br-
b. NH₄⁺ + OH⁻ → H₂O + NH₃
c. HCO₃⁻ + H₂O ⇌ CO₃²⁻ + H₃O⁺
d. KOH → K+ + OH-
e. HNO₃ → H⁺ + NO₃⁻
f. Al(OH)₃ → Al³⁺ + 3OH⁻
g. H₂SO₄ + H₂O ⇌ H₃O⁺ + HSO₄⁻

Answer 1

HBr and HNO₃ are Arrhenius acids, OH⁻ and NH₃ are Arrhenius bases. HBr, NH₄⁺, HCO₃⁻, H₂SO₄, and HNO₂ are Brønsted-Lowry acids. OH⁻, NH₃, H₂O, HSO₄⁻, and HCO₃⁻ are Brønsted-Lowry bases.

Step-by-step explanation:

In the given reactions, the substances that correspond to Arrhenius acids are HBr and HNO₃, while the substances that correspond to Arrhenius bases are OH⁻ and NH₃.

The substances that correspond to Brønsted-Lowry acids are HBr, NH₄⁺, HCO₃⁻, H₂SO₄, and HNO₂, while the substances that correspond to Brønsted-Lowry bases are OH⁻, NH₃, H₂O, HSO₄⁻, and HCO₃⁻.
