Reaction of Metallic Oxides with Acids

Activity 2.7- Take a small amount of copper oxide in a beaker and add dilute hydrochloride acid slowly
while stirring.
 Note the colour of the solution. What has happened to the copper oxide?
Observation- The colour of the solution becomes blue-green and the copper oxide dissolves.
Explanation & Conclusion
The blue-green colour of the solution is due to the formation of copper(II)chloride.
Metal oxide ( here - CuO) reacts with an acid to produce salt and water, this is a neutralisation reaction.
So metal oxides are basic in nature.
2HCI + CuO →CuCI2 + H2O
