These oxides are called amphoteric because they can dissolve in acidic solutions to form metal cations in the solutions but can also dissolve in strongly alkaline aqueous solution to form oxyanions of the metals: aluminate or zincate.

Aluminium and zinc oxides are called amphoteric oxides because they can react as both acids and bases. This means they can react with both acids to form salts and water, as well as with bases to form salts and water. Their ability to exhibit acidic and basic properties makes them versatile compounds in chemical reactions.

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.
What is amphoteric oxides?
Amphoteric oxides are compounds that can act as both acids and bases, meaning they can react with both acids and bases. These oxides exhibit this behavior depending on the reaction conditions. Examples of amphoteric oxides include zinc oxide and aluminum oxide.
What are amphoteric metals?
Amphoteric metals are elements that can act as both acids and bases in a chemical reaction. This means they have the ability to donate or accept a proton depending on the reaction conditions. Some examples of amphoteric metals include aluminum, zinc, and lead.
Oxides that are both acids and bases?
Amphoteric oxides can act as both acids and bases. These oxides have the ability to donate or accept a proton depending on the reaction conditions. Common examples include aluminum oxide (Al2O3) and zinc oxide (ZnO).
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.
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.
Which oxides react with both acids and alkali to give salt and water only?
Amphoteric oxides are oxides that react with both acids and bases to form salts and water only. Some examples of amphoteric oxides include aluminum oxide (Al2O3) and zinc oxide (ZnO).

What are amphoteric metals?
Amphoteric metals are elements that can act as both acids and bases in a chemical reaction. This means they have the ability to donate or accept a proton depending on the reaction conditions. Some examples of amphoteric metals include aluminum, zinc, and lead.
What are the characteristics of oxide?
They are usually dull and brittle, form crystals and are insoluble (apart from potassium, sodium, lithium and ammonium oxides). Metal oxides are largely basic. Non-metal oxides are acidic. Aluminium and Zinc oxides are amphoteric (can act as a base or and acid by being able to both donate and accept protons.)
What are examples of amphoteric oxides?
From the USDOT Pipeline and Hazardous Materials Safety Administration Glossary: A metal that is susceptible to corrosion in both acid and alkaline environments. Aluminum is an example of an amphoteric metal.

Is magnesium oxide amphoteric?
Yes, magnesium oxide is amphoteric, meaning it can react both as an acid and a base. It can react with both acids and bases to form different compounds depending on the conditions.
What name is given to those metal oxides which show basic as well acidic behaviour?
Amphoteric oxides are metal oxides that exhibit both acidic and basic behavior depending on the pH of the solution. Examples include zinc oxide and aluminum oxide.
Is zinc an amphoteric substance?
No, zinc is not an amphoteric substance. Amphoteric substances have the ability to react as both an acid and a base, while zinc typically acts as a Lewis acid, accepting electron pairs in chemical reactions.
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).
