Answer to Question #329839 in General Chemistry for Kidus

Question

In each of the reactions listed below, identify the Bronsted-lowery acids?

a. CH₃COOH (aq) + H₂O (l) CH₃COO^-(aq) + H₃0⁺ (aq)

b. HCN (aq) + SO4^-2 ↔ CN^-(aq) + HSO₄^-(aq)

c. HF (aq) + NH₃(g) ↔ F^-(aq) + NH₄⁺(aq)

d. HCIO₄(aq) + N₂H₄(aq) ↔ CIO₄^-(aq) + N₂H₅⁺(aq)

Answer 1

A Bronsted-Lowry acid is any species that can donate a proton (H⁺) to another molecule.

a. CH₃COOH_(aq) + H₂O_(l) ↔ CH₃COO^-_(aq) + H₃O⁺_(aq)

Bronsted-Lowry acid = CH₃COOH

b. HCN_(aq) + SO₄^-2 ↔ CN^-_(aq) + HSO₄^-_(aq)

Bronsted-Lowry acid = HCN

c. HF_(aq) + NH_3(g) ↔ F^-_(aq) + NH₄⁺_(aq)

Bronsted-Lowry acid = HF

d. HCIO_4(aq) + N₂H_4(aq) ↔ CIO₄^-_(aq) + N₂H₅⁺_(aq)

Bronsted-Lowry acid = HCIO₄
