TS EAMCET 5-Aug-2021 Shift 1 Question Paper

In‌CuSO4⋅5H2O,Cu is coordinated with 4 water molecules and two more oxygen atoms from sulphate ion.
Now fifth water molecule is hydrogen-bonded and is deeply embedded in a crystal. It is not coordinated to Cu.
Hence, only 4 water molecules are coordinated and the fifth is the only hydrogen bonded.
