The FT-IR spectroscopy was performed on pure zinc sulphate crystals to identify the presence of functional groups. The grown crystals have been subjected to powder X-ray diffraction to determine the unit cell dimensions and the crystal structure. The lattice parameters are found to be‚ a = 9.9810 Å‚ b = 7.2500 Å and c = 24.2800 Å‚ respectively. The values were in good agreement with those of the reported values. The
