Question

Explain the following by giving examples
(a) How metal oxides react with acids?
(b) How non- metal oxides react with base?

Answer 1

Answer:

a) How metal oxides react with acids?

answer - Metallic oxides react with acids to give salts and water. ... After the reaction takes place the colour of the solution becomes blue-green due to the formation of copper

Answer 2

Answer:

(a) Metallic oxides react with acids to give salts and water. ... After the reaction takes place the colour of the solution becomes blue-green due to the formation of copper (II) chloride and the copper oxide dissolves. This proves that metallic oxides are basic oxides.

(b) Non-metal oxides are acidic in nature. ... Therefore, when a base reacts with non-metal oxide both neutralize each other resulting production of salt and water. Base + Non-metal oxide ⇨ Salt + Water. Example: Sodium hydroxide gives sodium carbonate and water when it reacts with carbon dioxide.
