Question

Question 22 of 29 Which of the following reactions is an acid-base reaction? A) AgNO3(aq) + KF(aq) →→ AgF(s) + KNO3(aq) B) NH3(aq) + HF(aq) → NH4*(aq) + F(aq) C) NO₂ (aq) + Al(s) → NH3(g) + AIO₂ (aq) D) CH4(g) + 2O₂(g) → 2H₂O(g) + CO₂(g)​

Answer 1

The correct answer is B) NH3(aq) + HF(aq) → NH4*(aq) + F(aq). In this reaction, ammonia acts as a base and hydrofluoric acid acts as an acid.

Step-by-step explanation:

The correct answer is B) NH3(aq) + HF(aq) → NH4*
angle(aq) + F(aq).

An acid-base reaction is a chemical reaction that involves the transfer of protons (H+ ions) between an acid and a base. In this reaction, ammonia (NH3) acts as a base and hydrofluoric acid (HF) acts as an acid. The hydrogen ion (H+) from HF is transferred to NH3, forming ammonium ion (NH4+) and fluoride ion (F-).

This reaction can be represented as: NH3(aq) + H+ → NH4+ (base) (acid)
