Question

5. What would happen if a small amount of copper oxide is taken in a beaker and dilute HCI is added to it?

Answer 1

Answer:Yes reaction will take place

Explanation:

Copper does not react with HCl but copper oxide reacts. A metal oxide and acid gives a redox reaction

Hence CuO (s) +2 HCl(aq) = CuCl2 (aq)+ H2O(l)

Answer 2

Answer:

Soluble copper (II) chloride and water formed.

Explanation:

Copper oxide is a weak base so it easily react with dilute HCL . Due to this reason if a small amount of copper oxide is taken in a breaker and dilute HCL is  added to it then it forms Soluble Copper (II) Chloride and water. However,  copper does not react with dilute HCL
