Describe an activity to observe the reaction of metal oxides with acids. What do you observe ?

Explanation

1) Take a small amount of copper oxide (CuO) in a beaker and slowly add dilute HCl acid while stirring.
2) We will notice th at the copper oxide present in the beaker dissolves in dilute HCl and tl1e colour of tl1e solution becomes bluish-green.
3) The reason for this change is the formation of copper chloride in the reaction.
4) The general reaction is Metal oxide+ Acid`to` Salt+ Water.
5) In this reaction. metal oxide reacts with acid to give salt and water. This reaction is similar to the neutralization reaction.
6) ln this reaction metal oxide gives salt and water when it reacts with acid. Thus we can conclude that metal oxides are basic in N/Ature .
