Yes, it is amphoteric, at the same time it behaves like acid AND like base:
- it acts as an acid when in a base:
ZnO(s) + 2OH-(aq) +H20(l) -> [Zn(OH)4]2-(aq)
- it reacts as a base when in acid:
ZnO(s) + 2H+(aq) -> Zn2+(aq) + H2O(l)

Is zinc oxide an acid anhydride?
No. Zinc oxide is a amphoteric oxide.
Is magnesium oxide amphoteric?
No, only aluminum oxide, lead oxide and zinc oxide are amphoteric oxides.
What is a reagent to show that an oxide is amphoteric?
two of the reagents are aluminum hydroxide and zinc hydroxide.
Is gallium oxide basic or amphoteric?
Gallium Oxide is an amphoteric Oxide because it is just below Aluminum in periodic table which also gives amphoteric oxide Regards: Engineer Ahmad
What is the role of zinc oxide to he zinc oxide paste?
zinc oxide is antiseptic in zinc paste
Is zinc oxide an acid anhydride?
No. Zinc oxide is a amphoteric oxide.
Is magnesium oxide amphoteric?
No, only aluminum oxide, lead oxide and zinc oxide are amphoteric oxides.
What is a reagent to show that an oxide is amphoteric?
two of the reagents are aluminum hydroxide and zinc hydroxide.
Which elements form amphoteric oxide?
Aluminium, Silicon, Zinc, Iron, and many more
Why zink oxide is called amphoteric oxide?
An amphoteric metal oxide is the oxide of a metal that can form either simple metal cations or oxyanions, depending on reaction conditions. If zinc oxide is reacted with a stong acid, a simple zinc salt including the anion of the reacting acid will form. In contrast, if zinc oxide is reacted with a strong alkali, a zincate salt containing the anion ZnO2-2 along with the cation of the strong alkali will result.
What means that it can act as an acid or base?
These are called amphoteric. They can react and neutralise both acids and alkalis. Such examples include aluminum oxide, zinc oxide and beryllium oxide.
Is aluminmum oxide an amphoteric oxide?
Yes it is an amphoteric oxide as it has both basic oxide and acidic oxide properties.
Four types of oxides and give example?
Acidic oxide, e.g. sulphur dioxide Basic oxide, e.g. iron oxide Neutral oxide, e.g. water Amphoteric oxide, e.g. zinc oxide
How do you separate copper from copper oxide?
I think you mean how do you extract copper from copper oxide, if so here's your answer. Take your copper oxide and heat it with something that is more reactive than copper. Carbon is a good example. The more reactive carbon will oxidise, taking the oxygen from the copper oxide leaving copper. copper oxide + carbon --> copper + carbon dioxide 2Cu0 + C --> 2Cu + CO2
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.
Is gallium oxide basic or amphoteric?
Gallium Oxide is an amphoteric Oxide because it is just below Aluminum in periodic table which also gives amphoteric oxide Regards: Engineer Ahmad
How do you classify the oxide of aluminum?
Amphoteric oxide.
