Zinc oxide (Zno) is considered as amphoteric because it can react withboth acid and base, for example:Reaction 1: Zno + H;SO,Reaction 2: Zno + 2 NaOH + H;0 >→ ZnSO, + H;ONaz[Zn(OH).]Discuss the above two reactions under the context of (a) Brønsted-Lowry;(b) Lewis and (c) Lux-Flood definition of acid and base.

a) As per Bronsted-Lowry theory, an acid is a substance which can donate a proton, and a base is a…

Zinc oxide (ZnO) is considered as amphoteric because it can react with both acid and base, for example: Reaction 1: ZnO + H;SO, → ZnSO, + H;O Reaction 2: ZnO + 2 N2OH + H;0 → Naz[Zn(OH)A] Discuss the above two reactions under the context of (a) Brønsted-Lowry; (b) Lewis and (c) Lux-Flood definition of acid and base.
