`CuSO_(4).5H_(2)Oundersetto(100)^(0)C[X](S) undersetto (250^(0))C[Y](S)`

A

`X` and `Y` are `CuSO_(4).3H_(2)O` and `CUSO_(4)`

B

`X` and `Y` are `CuSO_(4).3H_(2)O` and `CUSO_(4).H_(2)O`

C

`X`and `Y` are `CuSO_(4).H_(2)O` and `CuSO_(4)`

D

`X` and `Y` are `CuSO_(4)` and `CuO`

Text Solution

Verified by Experts

`CuSO_(4).5H_(2)Oundersetto(100)^(0)CuSO_(4).H_(2)O(s)undersetto(250)^(0)CuSO_(4)(s)`
So, (C ) option is correct.
