Question

what are amphoteric oxides ? give importance of alloy.
​

Answer 1

Explanation:

Those oxides that behave both as acidic and basic oxides are called amphoteric oxides.

Examples: Aluminium oxide (Al2O3), zinc oxide (ZnO)

Answer 2

Answer:

Here's ur answer

Explanation:

Metal oxides which react with both acids as well as bases to produce salts and water are known as amphoteric oxides. Many metals (such as zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. Amphoterism depends on the oxidation states of the oxide.

Alloys are made to: Enhance the hardness of a metal: An alloy is harder than its components. Pure metals are generally soft. The hardness of a metal can be enhanced by alloying it with another metal or nonmetal.
