How do metallic oxides react with Acids?
- Metallic oxides are basic in nature. They react with acids to give salt and
- Copper oxide is a metallic
- When dilute hydrochloric acid is added to a beaker containing a small amount of copper oxide, the copper oxide dissolves. The colour of the mixture becomes bluish-green because of the formation of Copper(II)
The reaction taking place in this experiment is
𝑪𝒖𝑶(𝒔) + 𝟐𝑯𝑪𝒍(𝒂𝒒) → 𝑪𝒖𝑪𝒍𝟐(𝒂𝒒) + 𝑯𝟐𝑶(𝒍)
Copper Oxide Green Solution of Copper (II) Chloride
- It is a neutralisation reaction in which the solid copper oxide reacts with hydrochloric acid to produce a soluble salt copper(II) chloride and
This can be generalized as
Metal Oxide + Acid → Salt + Water
How do non-metallic oxides react with Bases?
- Non-metallic oxides are acidic in nature. The reaction of a base with a non-metallic oxide will result in salt and
This can be generalized as
Base + Non-metallic Oxide → Salt + Water
- Carbon dioxide is a non-metallic
- When carbon dioxide is reacted with lime water or sodium hydroxide, it gives water and calcium carbonate, a
The reaction taking place in this experiment is
𝑪𝒂(𝑶𝑯)𝟐(𝒂𝒒) + 𝑪𝑶𝟐(𝒈) → 𝑪𝒂𝑪𝑶𝟑(𝒔) + 𝑯𝟐𝑶(𝒍)
(Lime water) (White precipitate)
