What are amphoteric oxides? Give examples. State ways to prevent rusting.
Answers
Answer:
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.
Explanation:
Examples are =zinc, tin, lead, aluminium, and beryllium
The ways to prevent rusting are as follows ;
1) Paint it - Paint the metal with any durable acrylic paint.
2) Keep moisture at Bay - Avoid contact with water or moisture.
3) Coat it with Oil - Use of oil or grease significantly reduces the chances of developing rust in iron.
