What are amphoteric oxides give exam?
Amphoteric oxides react with both acids and alkalis to form salt and water. Examples of amphoteric oxides are zinc oxide and aluminium oxide.
What happens when amphoteric oxides?
Amphoteric oxides are classified as metal oxides, which react with both acids and bases as well to create water and salts. Amphoteric oxides are oxygen compounds, which show both basic and acidic characteristics. These oxides undergo a neutralization reaction to produce water and salt as they react with acid.
What is an amphoteric oxide give an example show by chemical equations that the given example is an amphoteric oxide?
Amphoteric oxides can be defined as oxides that can behave as an acid as well as a base to produce a salt and water. It can either donate or accept a proton or H+ ion thus acting as base or an acid. A common example of amphoteric oxide is zinc oxide (ZnO).
What are amphoteric oxides used for?
Amphoteric oxides dissolve in water to form alkaline solutions. Alkaline solutions contain hydroxide ions. Thus aluminium oxide (Al2O3) reacts with hydrochloric acid to form aluminium chloride and water.
Why are some oxides amphoteric?
An amphoteric oxide is an oxide that can act as either an acid or base in a reaction to produce a salt and water. Amphoterism depends on the oxidation states available to a chemical species. Because metals have multiple oxidation states, they form amphoteric oxides and hydroxides.
Is CuO an amphoteric oxide?
CuO: It is a basic oxide. Thus Cu does not give amphoteric oxide.
Is CaO an amphoteric oxide?
Calcium oxide is not an amphoteric oxide rather $CaO$ is a basic oxide and when it reacts with acid, salt and water are produced.
What do you mean by amphoteric oxide explain with chemical reactions?
What are amphoteric oxides give two examples write balanced chemical equation to justify your answer?
Oxides which react with both acids and bases to give the respective salt and water are called Amphoteric oxides. Example: Zinc oxide, Aluminium oxide.
