isothermal evaporation method. ZnSO 4.7H2O is highly soluble in water and the solubility is found to be increased almost linearly with the increase of temperature. At room temperature around 34C‚ the solubility was found to be 92.41 gm/50 ml. 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

H2O vs H2O2) * Law of conservation of mass: atoms cannot be created or destroyed during a chemical reaction

Synthesis of Isopentyl Acetate (Banana Oil) Using A Fischer Esterification Reaction Purpose: The purpose of this experiment is to synthesize Isopentyl Acetate using a Fischer esterification reaction. Fischer esterification is an acid-catalyzed condensation of an alcohol and a carboxylic acid‚ yielding an ester and water. Isopentyl Acetate has the scent of banana oil‚ once synthesized it will be purified by distillation. Then the analysis of the sample using H NMR and IR will determine purity

point of the steam distillation was to use an azeotrope to isolate the organic compound from a solid. The azeotrope was the liquid mixture with a constant boiling point. After obtaining pure eugenol‚ the percent recovery was calculated and an IR spectroscopy was performed.

What holds the complexes together: The set of ligands are held to a metal ion by largely electrostatic forces (although there really is a high degree of covalency). The forces arise from the positive charge on the metal ion and the electric dipoles of the ligands‚ whose negative ends are associated

Conductivity in metal-organic frameworks Metal–organic frameworks (MOFs)‚ are a class of crystalline materials whose crystal structure is made up from metal-containing clusters connected by multidentate organic linkers1‚2. MOFs are attracting considerable attention due to the possible rational design of crystal structures of coordination frameworks with versatile metal ions and organic ligands. In principle‚ MOFs topologies along with intermolecular distances between various building blocks can be
