Question

The coordination number of copper in CuSO4.5H2O is,

Answer 1

Answer:

Explanation:

In CuSO4.5H2O, four water molecules are coordinated to Cu+2, while one is hydrogen bonded with SO42-. Copper sulfate pentahydrate contains copper(II) in a geometry best described as distorted octahedral.

Answer 2

Answer:

The coordination number of copper in CuSO₄.5H₂O is four.

Explanation:

The oxidation number of Cu in CuSO₄.5H₂O is +2.

CuSO₄.5H₂O is a crystalline copper(2) sulphate with a square planar structure in which four water molecules are coupled to the centre copper cation.

Hydrogen interactions between a sulphate anion and a coordinated water molecule hold the fifth water molecule in place. The fifth hydrogen-bonded water molecule is entrenched firmly in the crystal lattice and thus hard to remove.
