Identify the incorrect statement.

A

`CuSO_(4)` reacts with KCl in aqueous solution to give `Cu_(2)Cl_(2)`

B

`CuSO_(4)` reacts with Kl in aqueous solution to give `Cu_(2)l_(2)`

C

`CuSO_(4)` reacts with NaOH and glucose in aqueous medium to give `Cu_(2)O`

D

`CuSO_(4)` on strong heating gives CuO.

Text Solution

Verified by Experts

The correct Answer is:
A
(A) `CuSO_(4)` reacts with Kl to give `Cu_(2)l_(2)` (white precipitate) but not with KCl.
(B) `2Cu^(2+)+4I^(-)toCu_(2)I_(2)+I_(2)uarr`
(C) Fehling's solution mainly contains `CuSO_(4)` and NaOH. When warmed with blucose (with `-CHO` group) gives red precipitate of `Cu_(2)O` Glucose reduces the `Cu^(2+)` to `Cu_(2)O` (red). ltbr. (D) `CuSO_(4)` on heating gives CuO.
`CuSO_(4)overset(1000K)toCuO+SO_(2)+(1)/(2)O_(2)`.
