How many water molecule in CuSO4.5H2O attached only by coordinate bond?
The Attempt at a Solution
Copper exists in the form of Cu2+. So, it has one vacant d-orbital. The answer should then be 1. But it's 2 :(
The chemical formula for CuSO4.5H2O is copper(II) sulfate pentahydrate. This means that it contains one copper atom, one sulfur atom, four oxygen atoms, and ten hydrogen atoms.
There are five water molecules in one unit of CuSO4.5H2O. This is indicated by the "5H2O" in the chemical formula.
The water molecules in CuSO4.5H2O play a crucial role in the structure and properties of the compound. They are necessary for the formation of hydrated copper(II) sulfate crystals and help to stabilize the structure of the compound.
The presence of water molecules in CuSO4.5H2O affects its physical and chemical properties. It increases the solubility of the compound in water and also changes its color from white to blue. The water molecules also help to lower the melting and boiling points of the compound.
Yes, the number of water molecules in CuSO4.5H2O can vary. This compound exists in different forms known as hydrates, which have different amounts of water molecules. For example, CuSO4.3H2O is a different hydrate of copper(II) sulfate that contains three water molecules instead of five.
