“WATER IS A GOOD SOLVENT” Water is very unique in all facets of its nature. The chemical formula for water is H2O as a water molecule consists of two atoms of the chemical element hydrogen (H) and one atom of the element oxygen (O). Water is the most abundant chemical compound on earth as its mass all exists together‚ naturally‚ in its gaseous‚ liquid and solid state. It is the most precious natural resource to man and is essential to life for all discovered living organisms. One of the unusual

The influence of the concentration of La3+ was studied using increasing volumes of a 5.1×10-4 M solution in the range of 0.05 – 2.0 mL of the reagent. The tested diluting solvents included water‚ dimethyl sulfoxide‚ acetonitrile‚ dioxan‚ ethanol‚ methanol‚ and 2-propanol. After mixing the studied drug solution with all reagents‚ the reaction mixture was allowed to stand at room temperature for different time interval and the fluorescence intensity
