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?
Elements that form amphoteric oxides have the ability to react with both acids and bases. Common elements that form amphoteric oxides include aluminum, zinc, lead, and tin. These elements can exhibit both acidic and basic properties depending on the environment in which they are placed.
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?
A substance that can act as both an acid and a base is called amphoteric. This means it can donate or accept protons depending on the reaction it is involved in. Water is a common example of an amphoteric substance.
Is aluminmum oxide an amphoteric oxide?
Yes it is an amphoteric oxide as it has both basic oxide and acidic oxide properties.
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
Four types of oxides and give example?
Basic oxides: Examples include sodium oxide (Na2O) and calcium oxide (CaO). Acidic oxides: Examples include sulfur dioxide (SO2) and nitrogen dioxide (NO2). Amphoteric oxides: Examples include zinc oxide (ZnO) and aluminum oxide (Al2O3). Neutral oxides: Examples include carbon monoxide (CO) and nitric oxide (NO).
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 zinc an amphoteric substance?
zinc reacts with acids as in: Zn+H2SO4-ZnSO4+H2 zinc also reacts with bases as in: Zn+2NaOH - Na2ZnO2+H2 Therefore zinc should be amphoteric metal. But none of the sites states that zinc is amphoteric
Beryllium oxide is amphoteric prove with examples?
Yes, beryllium oxide is amphoteric because can be dissolved by acids and bases..
