In the formula of crystalline CuSO4 I.E.:-CuSO4.5H2O, wHAT DOES THE 5H20 STANDS FOR???
5H2O stands for the dehydration of copper sulphate.it shows that copper sulphate solution is hydrated.

The 5H2O in the formula CuSO4.5H2O represents the presence of water molecules within the crystal structure of copper(II) sulfate. These water molecules are referred to as "water of hydration" or "water of crystallization." The number 5 signifies that there are five water molecules associated with each copper(II) sulfate unit in the crystal lattice.
To understand how to interpret this notation, it's helpful to break it down:
- CuSO4: This is the chemical formula for copper(II) sulfate, which consists of one copper (Cu) atom, one sulfur (S) atom, and four oxygen (O) atoms.
- 5H2O: This means that for every one unit of CuSO4, there are five units of H2O. Each H2O represents one water molecule composed of two hydrogen (H) atoms bonded to one oxygen (O) atom.
So, the complete formula CuSO4.5H2O indicates that each unit of copper(II) sulfate crystal contains five water molecules.
