What Is The Structure Of CrSO4.3H2O?

The structure of CrSO4.3H2O, also known as chromium(III) sulfate trihydrate, consists of one chromium ion (Cr3+) at the center, surrounded by six water molecules and three sulfate ions (SO42-). The chromium ion is coordinated with six water molecules in an octahedral arrangement, while each sulfate ion is connected to two chromium ions through oxygen atoms. The compound's formula indicates that there are three water molecules per unit of chromium(III) sulfate, making it a hydrated salt. The presence of water molecules in the crystal lattice affects its physical properties, such as solubility and melting point.
