Answer:

Lewis Acid model definition (for acids that contain H⁺ and bases that contain OH⁻) is wide than that of Bronsted–Lowry model.

Step-by-step explanation:

  • According to Bronsted–Lowry model:

Acids are proton donors (H⁺).

Bases are proton acceptors (OH⁻).

  • For acids that contain H⁺ (HCl) and bases that contain OH⁻ (NaOH).

  • According to Lewis Acid Model :

Acids are electron pair acceptors.

Bases are electron pair donors.

  • It is widely used for define acids and bases:

BF₃ + NH₃ → BF₃-NH₃.

BF₃ is acid that is electron acceptor which accept electrons from NH₃ (electron donor).
