Zinc(II) ion reacts with aqueous ammonia to precipitate white gelatinous Zn(OH)2: Zn2+(aq) + 2NH3(aq) + 2H2O(l) <==> Zn(OH)2(s) + 2NH4+(aq)
The zinc(II) hydroxide precipitate dissolves in excess ammonia: Zn(OH)2(s) + 4NH3(aq) <==> [Zn(NH3)4]2+(aq) + 2OH-(aq)
The zinc(II) hydroxide precipitate also dissolves in hydroxide: Zn(OH)2(s) + 2OH-(aq) <==> [Zn(OH)4]2-(aq)
It also react with acids!

What Amphoteric species?
Amphoteric species are substances that can act as both an acid and a base, depending on the reaction conditions. They can donate or accept protons, allowing them to exhibit both acidic and basic characteristics. Water is a common example of an amphoteric species.
Is sodium hydroxide a common or proper noun?
Sodium hydroxide is a common noun. It refers to a compound composed of the elements sodium, hydrogen, and oxygen.
What is an Amphoteric substance?
Amphoteric Substance is one that can react as either an acid or base."Partly one and partly the other; neither acid nor alkaline; neutral" (I don't think this answer is correct)The word is derived from the Greek prefix ampho- meaning "both".Many metals (such as zinc, tin, lead, aluminium, and beryllium) and most metalloids have amphoteric oxides. Other examples include amino acids and proteins, which have amine and carboxylic acid groups, and self-ionizable compounds such as water and ammonia.
