Question

Assertion (A) : When we add dilute HCl in CuO, The color of the solution changes.
Reason (R) : The color of the solution changes because of the formation of Copper chloride in the reaction.
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true.​

Answer 1

Answer:

A

Explanation:

The reaction leads to the formation of Cu(Cl)2 which is soluble hence it would show light blue color due to the presence of Cu+2 ion

2HCL+CuO-Cu(Cl)2(aq) + H2O

it is similar to addition of water to Cu(SO)4 anhydrous which is white and later turn blue due to aqueous Cu+2 ion
