Just random thoughts coming to my mind...

1) We know tht in CuSO₄.5H₂O 4water moecules are coordinated n 1 is H-bonded.
So when the hydrated salt is heated, initially, one water molecule remains. Is this the H-bonded one ?

2) In bleaching powder, CaOCl₂, is Chlorine in "0" oxid.n state ?
I've heard smthing like one Cl is in +1 n the other in -1, so its avg. O.S. is zero. Is tht rite ?

2)
On an average,O.S of Cl is 0.

Tht means it is actually like -
CaOCl⁺ Cl^- & not Ca ²⁺OCl₂^2-....?

2) CaOCl₂ exists as CaCl(ClO)
i.e. two anions Cl^- and ClO^-

So oxidation states are -1 and +1 respectively

Presence of ClO^- can be confirmed by adding a stronger acid eg. sulfuric acid
